I'm gonna change out my turbo to downpipe v-band clamp, might have a suspect area idk yet. When I checked flow cause I didn't see pressure, had flow and didn't have any foam etc, however didn't have a looped clear tube to be more precise. Idk how many times I've done valve lash in the past couple of months, but I'm gonna do it again anyway. Idk if I should pop those injectors out anyway and get them testes and re popped at 320 bar. All my little points I made lead to injectors from what I can see?

Bump for some Sunday thoughts?

Dumb question, will vibrating or (over vibrating) lines cause any injection issues? Just a tid bit...The new line set I got didn't exactly line up with what I consider factory, the hardware mounts/locations are not factory either but I made it work regardless. Lines are very close to each other but I gentle massaged them to were there atleast not touching. I noticed today that I can hear what sounds like a syringe being pressed quickly making that hard squirt sound if that makes sense. Yes I know squirt/injection sa.e thing but this didn't sound right to me. I'll attach a sound clip, obviously capturing exact replicas of sounds is difficult to do but... #3 & #4 injection lines vibrate more and you can feel a harder pulse on them too... This makes me think once more that the injector are bad AGAIN! Idk?!?! I also can hear what sounds like a dud/light miss at around 2200 and also again at another rpm but I can't remember right now. This is with the quad on zero... This all falls in line with the noise I hear while driving interstate, sounds like timing but also sounds like valve issue or something or like a half working injector... If you can conjure up that noise/feeling in your head. Just too hard to describe. The quad in zero doesn't have any more smoke than my tune and still has some get up?!?! Why no more smoke with the absense of added timing, questionable... Fail on me I haven't chatted with the guy to do my ecu yet but in the works.... With that white smoke on start up and pretty good haze on startup there after for a bit if idling. Also to note AGAIN I haven't had any dark smoke like one would see with big injectors ever! Idk why but I think you would notice it should at some point............. Still haven't figured out timing... moved from 15, 19, 25, 28, 30 to 14, 18, 22, 26, 28... with no change really to speak of. I'll pay you to come tune it haha, even give you a place to stay. Lots to take in, main thing that could be an issue is bad injectors, tune already on ecu, valvetrain issues, lines, timing. Idk. Can't figure out how to separate the timing from valvetrain issues or valve for that matter. Anyway just an update please respond with any help! Recording_9.wav Edit: I forgot to mention that when you first start up that it sounds like normal for a revolution then drops down real low then picks back up, 20% of the time it might die---- ithimk this ties into the fuel pressure issue I'm having on gauge, injector bleeding off??? Also to add to this is the white smoke on startup, and the other issue mentioned previously. Am I crazy or does this chalk up to the injectors again? Like I've said previously the sounds I've heard way back in conversations all differ from injector sets going bad and intern being bad. Most noticeable sound now is heard around 2100-2200 rpm (loudest) but also heard all around...

I been thinking of getting into a gaming PC myself, ditching the PS4-5 units you have to buy every so often, comp you just upgrade. Definitely very interesting!

Stupid question, does fuel stretch matter if your not running a wire tap? What does matter in that (wire tap) section on the quad?

That's one of those tips to put in the tip section we were talking about I think it was @LorenS that mentioned it.

So todays drive into work wasnt to bad. Egts were pretty decent too, could be better but so far its manageable. My oil temp is still same as coolant temp, as @Mopar1973Mansays. oil temp should be lower than coolant for proper timing. The iQuad still is confusing no matter how many times I read it, its like everything affects another thing which affects another. Kinda planning 2 steps ahead lol. So which do you work first? Timing only - which band? Or max load, low psi reduct, reduct scaling - seems to be either 50% or 100% for most people? I attached a snippet from this mornings drive in, at the end I gave it some throttle too, egt buzzer didnt ding at me yay! lol. iQuad-2022-04-18-05.28.20-579684091[1].csv

It might just be the gauge going. This morning done some micro testing and had to key bump twice before it showed pressure at the gauge, somethings bleeding off? The pump runs at any point, there's no problem there. I just dont see pressure till I key bump a few times or the truck starts. Its something that just started happening maybe a week or so ago... That silly {upgraded} spring has disappointed me. Still at that solid 15 psi which is good but I wanted 16-17psi for security. Ill have to do what @Mopar1973Mansuggested and find some washers that will fit inside there. Im assuming opposite side of check ball, on fitting side...

Sorry @Tractorman it is from (ECM) main harness LP plug to relay, then relay to LP.

Well I found a contact to call this week about my ecu, so that's in the works. I fixed my wastegate issue for now. Got it set at 55psi. Made a nice setup with a regulator right at the turbo. Here is the wastegate rod issue I mentioned previously. I pried more on it but it still isn't what I'd like to have. Very limited space! I will be monitoring egts and boost numbers this week and see what happens. I need to figure out that knock or what ever it is. I think it's valve train but at the same time, I've had a different noise everytime I've changed injectors. Which leads me to believe with the egts and noise it could be injectors? I'd almost put money on it! Only under load and/or higher rpms. Been doing research on lifters, and valve train issues. If it's valves I'm screwed, either way I'd have to pull head to be certain on most of it...

The FASS system plugs into the factory LP plug. Pump is running when these tests were done. Gauge is mechanical also. I did another couple of bump tests this morning and wouldn't you know the gauge showed 15psi... seems to be intermittent now... I'll have to monitor this week and see. It has shown the previous symptom all last week.

Exactly what I was thinking. Lol

I guess while we're talking shocks, anyone ever run a dual front shock setup? I have seen them on some high class rigs, didn't know why or if it helped. Just curious...

I'm gonna do some more key bumps in the morning and check again, but this worries me... I should have a constant pressure not 0... I might tweak their "upgraded" spring (shouldn't have to do this @fass) and add a washer maybe, if this little issue gets solved.

I think I would still recommend getting that kit big tires or not. My tires are only 33". I bought it once and I'll never have to buy any steering stuff again, and it's bullet proof.

I have CPP's 60" bolt on traction bars, work great, no more axle wrap for me. However I highly do not recommend buying from them anymore!

I'm running blistens - shocks and stabilizer and a DOR complete steering setup all heim joints. Solid as a rock, last to do is the gear box. Love the setup!

Thought I'd make another little one for this. Doing some diag and upkeep and stuff from other thread this weekend and came across this... So I can turn key on, visually see needle on gauge move 0-5 psi, next do a key bump and it shows nothing, no matter how any times I try key bump. I removed fuel line from vp44 and into a bucket. Performed key bump again, fuel flows out great fills up a gallon pail and then some. When truck is started gauge shows 15psi even while driving. I also have a spring kit from FASS to increase pressure just a tad. However I have never seen more than 16psi, only sits at 15. Idk why that is??? Stock is around 15, I was hoping for 17 ish... New vp44 came with a new overflow valve, could that be failing or failed causing this? I'm not sure what else it would be. Fass has flow but can't build any pressure maybe another idea, should still have warranty on it. Any thoughts?

No haven't tried that. I thought about seeing if I could get it re flashed,but I wanna make sure they will put my 3 cylinder high idle and high idle back on cause most won't... I mentioned to moparman that maybe there is a "tune" latched to it still from PO that he forgot, or forgot to tell me? Idk anything is possible. If there is any video or whatever I can make or provide let me know. Currently still at the provided: 15, 19, 25, 28, 30 The 90 up canbus fuel curve 2*, 5*, 50%, 2*, 28% (or 30%) Edit: I just thought of an old buddy that might be able to re-flash mine or possibly loan me one to test, I'll contact him today and check...

This is true, you make a valid point and completely see where your coming from. Probably very true and makes common sense 🤣 I'm not a young kid or an old fart yet, I'm right in the middle and still would like a little play time, I think alot can attest to that lol. I really think I would have a hard time selling my turbo, just don't know anyone and fb market place you get all kinds of riff raff from there; injectors I could prolly keep till down the road perhaps. I know I don't need what I got, I tried to make it better by getting smaller all NEW pump, lines, tubes, injectors and thought I'd be golden... not so much at the moment... I guess best case scenario I'd like to (make it work) best as possible till I can find a way/save up for twins and save what little money I have for that goal, whether it makes sense or I'm off my rocker idk. If I knew what an "acceptable" egt # would be that might help. Everything seems fine otherwise. Timing (might be a smidge high?) Or I have lifter knock, or what kinda sounds like valve or valve train knock, idk. Its very light though. Gets up and a scoots however! But 900 and 1000* just worries me @ cruise that is... There gain I could have bad injectors once more...dribbling or maybe that's the knock hmm 🤔

I went from the .093 lines and tubes back to stock... started with a DF pump, .093 lines and tubes, 6x18's, same turbo, cam, etc. Tried 6x18, 7x15, 6x13. Long story on all of it... now it's stock pump, lines, tubes, all new... 5th or sixth set of injectors from dap (new 6x13). Sig is up to date. That's the problem, I can't get it right. Been taking suggestions as they come, I'm just can't get the hang of all this via reading, I need taught via hands on and explanations... Just friggin difficult. I've tried only 65mph max every day, easing into the pedal, trying to get some mpg and egts down and level but it just isn't happening. Just better than What I've previously had and it's still the same.....

Well I had to try it lol but not even close. Truck barely moved haha. Back to the other one now. I don't think buying another turbo and another set of injectors is a smart idea, to then turn around and buy another turbo or 2 at a later date then have a turbo and injectors set just sitting around that I really didn't want or need in the first place. Just my take on it. I'd rather figure out how to make this one work till further upgrades can be had. So maybe I'll have to deal with egts above 600 idk. The other day there was a light head wind and I was 950-1050 all the way into town! If the quad is supposed to help and manage things to an extent and I can't get anything I'm needing that's it's supposed to do, maybe I'm on my 7th set of bad injectors??? Does anyone else have a similar setup and get better than 12 mpg and lower than 800-900 egt's cruising?? Sorry for the rant, just getting more irritated again that I can't seem to get this figured out and I'm frustrated. It's funny, I don't really remember my previous setup which was an insane amount of fuel ever getting hot as it does now 1400-1500* not even trying lol.

Gonna plug all that in here before I leave and test it out. Timing and fuel.

It seemed fine to me, like I was saying the boost numbers seem low to me, smidge of smoke through 3rd and 4th, not clouding out the intersection though. I think the obvious hindrance is the turbo spool down low, cause it's laggy up untiiiiiiillllllllll 2,000 rpm lol Engine supposedly has a Hamilton cam, can't 100% confirm but I assume it's there. Got a BD intake horn, and no grid heater going into the plenum Yall got me really wanting to throw some money at 2 turbos right now... That's gonna be expensive!! Anyone want a 64/71/14 ?🤣 (Wastegate works ust can't hook it up on mine)

Yes I knew they where big, just thought it was a better option than 6x18 haha... I guess I need to start figuring out/learning twins?!?! Daily play truck? I can live with it! 2k is indeed the area where it hits. However, I'm only hitting boost in the 30-40 psi range right now... not enough fuel yet?? Edit: I reference (only 30-40) just due to what I used to get with it. It could peg a 60 psi gauge... I think 70 mph is a good number for hwy cruise. In my wife's car it's 75 for all the interstate driving lol. I currently have only been driving/testing @ 65mph for all this. I'd rather 75 but let's face its got 4.10's....
