Zamboni

This exactly. I chose to dispute the violation for this reason. With the price of fuel I am not going to give up 20 MPG. The letter they sent me had a clause for engine not being to operating temp. My commute is less than 2 miles each direction, my truck never gets to temp unless it's cold out and I warm it up. I will get it to temp and they are going to put it on the dyno test and check it out. Then I have a meeting with the Environmental Health Scientist. He is like 25 years old, I have been a mechanic longer than he has been alive. Wish me luck.🤣

I have an old economy tune you had posted on here back in 2020ish. I have made a few tweaks over the years but I have been running it sine 2021 and it serves me well and doesn't smoke, that is why I think the claim is BS. I also use one of your old tow tunes that I have tweaked a little. works great for 12k lbs. Thank you for the advice, this site helped me tremendously in the past and I still peak once in a while.

Good idea on hiding the tuner. I believe that can be done and will be the way forward. Right now I am disputing the ruling since the county told me the tuner has always been illegal and they (the county) performed my emissions test for the past 12 years with nothing ever said about the tuner in plain site under the hood. As far as smoke, I have none. My tune is spot on and getting 20MPG not towing. I do have 100hp injectors but I also have a 62/64 DAP stage 2 towing turbo which cleans up any excess fuel without smoke. FYI most EDGE tuners are CARB compliant since the tunes are set and non adjustable. Thank you for your input. I am hesitant to change tuners because of the lack of timing adjustment. Some one turned me in to the county for excessive emissions from the tail pipe. I call BS since I know better, I think they were mad their BMW wouldn't keep up.

What is a good EPA or CARB certified tuner? Utah has changed some laws and the Adrenaline is no longer legal in my county.🤬 How are the Smarty tuners? Do they have any timing adjustment capabilities? Any experience with Edge Juice w/Attitude? Any suggestions are appreciated. Also, wasn't there somewhere to sell items on here? Anybody looking for an Adrenaline w/IQuad?

Im not sure on the stall. It came with a kit i bought, all the invoice says is dpc drm1 low stall converter. This problem may have started after converter install, i changed the turbo after 1st trip with new trans and noticed problem when i tried to get my 5th wheel back in my yard which is a slight incline.

It is the 3:54(55) rear end. We are about 4700ft. I think i will install my hy turbo and see if it makes a difference, that is a free and easy swap and that seems to be when the problem started. I only changed it to try and lower egts but no with the adrenaline they are under control.

I can hook up my scanner and check. That would make sense. Not sure why in reverse only but it is worth a try.

So i have the hx installed now. This problem seemed to evolve when i switched from the hy i think. I was thinkin hy would spool better due to smaller housing. May be something in trans but don't understand why just with weight.

In reverse under load rpms will not go above about 1200 and lots of black smoke. Rpm does not increase and engine does not stall. It just bogs down. Trans has a couple thousand miles on it with a single billet DPC converter, has no issues other than no reverse power with a load. Go just fine in reverse unloaded. Have had problem with 3 different trailer of various weights. Not sure where to go from here.

I use manual first all the time, there is no slippage. I pull a 12k pound trailer and start out in manual first and reach 30+ lbs of boost with no issues. It just won't push a trailer up a hill in reverse. I don't get it. I was ready to give up on this truck last year and decided to install the adrenaline now I'm second guessing that decision.

So the issue I'm having is i have no power in reverse, not transmission problem power but my truck will not push my 5th wheel trailer in reverse up an incline, just black smoke. So ever since i changed to an HX35 turbo and a lower stall torque converter this has been an issue. My thinking on this problem is the lower stall converter is not allowing the engine to increase in rpm to get any boost from the turbo. So question is, will my old hy35 spool better with this setup or would a stock or higher stall converter be a better option or am i just missing something?

Prior to having my injectors set to 320BAR i had changed the nozzles myself i thought it ran ok but did notice a slight rough idle, rough running at high RPMs while towing and high EGTs, after having the injectors built and set at 320 the truck idles very smooth and has no high RPM or EGT issues. My injectors had just over 100k miles and im pretty sure they were well below recommended pressures.

With this setup are you able to use the braking feature? I am picking up a 351ve tomorrow.

I'll keep that in mind. Thanks.
