2nd Generation Dodge Reliability / Performance

So here recently my trucks been loosing prime/fuel pressure after its been shut off and sits for a few hours, normally overnight. The other day it did in the 4 hours from when I got to work and left for lunch. This really bothered me, so after lunch I crawled all over her and checked all fittings to the fuel system I could get to. With no luck of something loose, I was not happy and dreading it bein internal. Pulled the dipstick and with 2k on this oil change, I was maybe a qt over full. This tells me that Ive got an injector thats leaking down after shut off. Truck runs and drives fine, no extra smoke at idle or drive, nor does it run any hotter. So finally to my …

Gonna prolly go ahead and get the quadzilla for my rig. Does the kit come with all sensors needed for monitoring or are they purchased separately? Or do I even need them? Does it come with a display screen? Just Kinda confused on what you get and what you need. I think there is a few threads on how to tune once I get it. I'll prolly have to ask then what would be best with current setup.

Where is the most reliable place to send in oil to have it tested? I have never done it before and would like to start checking it every so often. Is there any other fluids that should be tested? Thanks! I have done the antifreeze flush but not the break system or diffs

My first turbo diesel a 01 3500 w some modes to pull better. A Smarty programmer, S362 turbo, stk head bolts, stk injectors, 5' straight pipe exhaust axle dump, 3 piece exspantion joint exhaust manifold, BD exhaust brake. My questions are, when applying the exhaust brake exh. pressure will increase from flow restrictions causing heat to build up raising pressure even more, can the clamping force of stk exh. hardware or head bolts fail or stretch an loosen causing gaskets to move an leak? If possible can these press. be monitored and managed?

Question - does the chip matter when deciding between 100 and 150gph lift pumps? - If so, is it possible to figure out which chip/hp rating is installed? I took ownership of my truck in 2007, it belonged to my ex since 2005. He put a non-adjustable chip in the truck while we dated and shame on me for not remembering which one it was... I desparately need a new lift pump and afraid to buy the wrong one!

Im having issues with dead pedal. Dont know where to start?!? Its been getter worse. Was happening about once or so every few months....would forget about it, then it would happen again. An today it happened 4-5xs home from work(about 35kms). If i push in clutch an pump pedal a few times itl will come back....then randomly cut out again while just cruising( barely on the pedal). Wondering if this HOT summer weather has somthing to do with it?? Any direction would help thnx!

I’ve gone through the tuning process, and I like my boost level fueling curve. I also think I Ike my pump tap parameters, but I’m not sure my stock clutch can handle much wiretap at all. But all of my timing parameters are set to Mike’s economy settings. I’m going to lose sleep about not having ARP studs. I don’t really understand the timing settings, so I need them explained (dummy style) or I need to know how not to exceed recommendations for stock head studs. I’d like to get studs, but I’ve got to get on the road hauling my 7k pound camper here soon and don’t have the time or cash. I’ve done a lot of reading, but I just can’t quite get my head around the technica…

I know there has been talk about how few times an ECM goes out, not to worry about the engine heat and where it's mounted and so on. Except isn't it getting harder to find a good reliable one? Getting it flashed properly can be a problem also, I've heard. Then you have a few ECM rebuilders/ repair companies sending off faulty units. Sometimes being a crap shoot trying to get a good one. Some have reported bad experiences while their truck sits for days sending units back and forth till they get one that works.Now I have been Googling engine heat, ECMS and problems... finding reports about how heat does affect them. One ECM supplier reporting that the engine heat is the bi…

Morning all, I've been having some issues with my daily tune for my Quadzilla. I have +50hp injectors that are 4 yrs/20k miles old and have had the Quad for about 2 years now. I can't seem to tune out the smoke In the 0-5 psi area on tip in acceleration. Cruising is clean and at 0-3 psi but anytime I'm hitting a small hill or pulling out onto a road and getting onto it there's a decent haze its not a black out but its enough to be confused/concerned about. It doesn't seem to clean up until 15ish psi. I don't know if pop pressure would be low or if my injectors are a bad set. Also I could have sworn I saw @dieselautopower mention that they updated their injecto…

I tried posting this in the 4K tunes spot but it wouldn’t let me choose that. I went to the track this weekend and used the hang on tune from the website. I’m really confused now cause when the truck shifted into second gear I pressed my lock up switch for the torque converter and the truck dies down and then pulls hard but it takes it a second to pull. Also at the light I was spooling up and I could not get the truck to go over 20psi without it trying to cut power back. Any help would be greatly appreciated. Just trying to prove that Quadzilla is the way to go.

So I have a blue chip diesel Premium VP44 in the truck, last time I drove it it felt worse then my old with 300k or something on it.. Much slower... So I was curious, you can add like 7x13 injectors and pick up added reliability out of the vp itself by detuning it so it works less hard... but I heard that 7x10's are the max size injector you should go with for towing heavy. So I'm curious what it is in a 8 hole? And HP deferences. That said there are Turbonators for VGT S300'S, any idea how much you can pickup on these trucks with one of those? Like fuel only numbers? + upsize in turbo with the VGT? I heard it's like the old s364 before…

Ok guys, As you know I'm an old salt here, I've helped hundred of people, but now I've reached the rope with NAPA. I've bough several alternators thought them for various local customers with the famed torque converter lock up. And after 2 years with a new Napa alternator mine failed in late January. Due to my own error I misplaced that recipt so I bought another new one for $191. Yesterday night after 6 months and a few days this one gave up as well. The ac ripple would go from .05vac then started spiking to .12vac. I called the same NAPA dealer I always use and told them it was a warranty. When I got there, they informed me that a 'lifetime' warranty was a o…

Anyone heard good from them? My new AD100 is squeaking loud enough and when it squeaks it looses fuel pressure but comes right back for a moment. I hope they treat me right. It's only got 7,000 miles on it. - - - Updated - - - They wanted to send me another pump but, they wanted my credit card number for shipping. I told them I don't have credit cards and would rather have my money back unless you can convince me you are building the pump like the old days when it was reliable and last longer than 7000 miles. That's when he hung up on me. Now this is a bunch of BS. AND THEY BARELY SPEAK ON THE PHONE... so you can't understand what they are saying…

hi all, reecenty registered guy been reading a lot to keep the questions to a min. but i know this is a big question so thanks in advance for any advice. i have a 01 dodge 24v 4x4 auto with 210,000 mi all stock except for a new edge ez, BHAF, replaced the vp fuel pump around 100,000mi ago, other than than its just been maintaince. im looking to get better performance when towing my new to me 9000 lbs toy hauler. i know i need guages asap, after that thinking 4" turbo back exhaust, injectors? (50hp? 75hp?), trans upgrades? and finally airdog or fass and what size?again just looking to make a good reliable tow rig that hopefully wont brake the bank. im pretty mechinical and…

ok people, lol, i have a 2001 dodge cummins with a edge comp box, air dog raptor pump and i just installed a 63mm turbo on it and this afternoon i noticed that my airdog raptor sounded really sick, slow and idling at 10 psi instead of the 20 i have it set to..... it has been bothering me cause i blew about 3 fuses today and its about 95 degrees out in the great state of texas!!! i checked everything and the batts seem good the truck starts without any problem the batts are runnig at 12.5v shut down... any ideas any one? lol:banghead:

Took the mighty Dodge on its first road trip today. Over 249 miles, in rain with lots of 65-45 braking for the first 90 miles i got 16.57 mpg. After the rain cleared we got free of traffic and had cruise set at 70-75 most times. Tried to data log but couldn't, I'll have that fixed for the return trip. I will get some data and hope some people here can help me with a tune.

Looking for some opinions I'm running a modded hx35 63 68 ported 12 now here's what I'm thinking tater built 67 68.9 12 with the hx40 down pipe or go s300 ball bearing 64 71 12 both companies say there turbo will spool faster then mine tater built builds a version of my turbo and said he can get the 67 to spool faster with a 7 blade compressor ECT the tater built Is also cheaper and no I'm not going smaller I like my turbo but always want more so any one got opinions I don't want to have to compound it I want stock appearing

Well i finally got to tow a good amount of weight than i ever do to Vegas from LA. Towed a steel enclosed car trailer that weighed in at about 10500 with the car. Now being steel wasn't the big problem but being that its got 8 ft ceiling inside was. Almost twice as high as the truck. Anyway the way there we averaged about 60-65 mph and about 50-55 on the steep grades. Kept the egts below 1100 going up the steep grades. Finally when we got to vegas had to fill up so hand calculated the mpg and it was about 9-10. Now on the way back topped off and weighed everything and came in at 16700. We had a crap load of rear axle weight over 5000 lbs and over 3000 in front. To much to…

So just wondering if anyone's heard of any problems towing with the xzt on level 3? Reading through some of the manuals for the edge ez and it recommends NEVER towing on level 3 and with these two boxes being quite similar it got me wondering. Not sure if that's just a legal/responsibility thing that they use to cover themselves when people try turning up the power and towing and causing damage to their trucks or what, but just wanted to see what you guys thought.

So I was doing some checking on my boost pressure and was see what the turbo would produce. I’m producing around 43lbs according to the manual gauge and 37 acorrding to the quad at wot. I then clamped the waste gate line and there was no increase. The turbo is maybe a month old now. So my questions are, with the stock injectors is that all I’m going to see if I’m not put out enough fuel? My next question is by crimping the waste gate off shouldnt I see more boost? I talked with bd diesel today and the guy said that with the turbo I have the optimal operating range is is 37-45 lbs. last question for now is, is there something wrong with the turbo if I can’t produce any mor…
