Hello. I have been searching the forum and online. I even ask people. I don?t get a straight answer. So here I am. Asking who I should have first . I have a 03 5.9 drw. I bought the truck with some upgrades. But motor wise stock. What I was told. No tune no tuner but has +70hp injectors. So it smokes like a loaded down semi. Even at idle I can see a haze from tail pipe. As soon as I give it throttle. Light or heavy. It pukes black. Without redoing injectors I would like to dial the fuel back a bit as my plan is in near future. I already have just have to clean it and install a 451vgt turbo. I have the stand alone computer for it But as the truck sits this is what I have
03 3500 drw
Stock turbo
Cold air
70hp injectors
Fas fuel
4? turbo back
Upgraded torque converter
I?m assuming the smoke is from over fueling with stock tune
For motor wise that?s it. Future plans. Head studs and 451vgt turbo , 6 level sotf switch and maybe put a muffler back in lol any one with info would be great as I started to go through the software and I got more lost lol. I?m just scared if I take too much fuel away that I will hurt the motor
Thanks
