- Truck Year
Ahh, quiets down the injectors, I have an upgraded intercooler and all 3in hot cold piping, so winter time I need all the help I can get to keep it warm.
So have you seen any gain in anything as far as performance or fuel mileage with deleting the butterfly?I got in contact with their support team and they said that they can reprogram the tune to delete that valve as well, but it will run me another $100. I'm guessing it's because they have to get back into the coding, as I didn't state that I wanted this deleted when I first got the tune. I don't think I'm going to get it though, as I haven't had any more trouble with it going into limp mode. What I did is I hooked up my OBD scanner then took the truck out on the highway and got as fast as I could get the truck (in limp mode). I would then shut the engine off and put the gear into neutral and as fast as I could I would delete the code. This would get the truck out of limp mode where I would then accelerate with my foot stomped on the floorboard. 95 I think it got before going into limp mode again. I repeated the same process until a "Check Engine" light came on and the truck stayed out of limp mode. At this point though, the lightning bolt dummy light was still present, as was the yellow Check Engine light. I parked the truck and deleted the code once more, then got back on the highway, and no lights or warnings popped up again.
