Re: Tuning issue or Injector issue?
This sounds EXACTLY how my truck was running as soon as I put the stage 2's in it. All the drivability symptoms you've described were the same as mine. I tried testing and replacing everything that I thought could have been screwed up after the install.... idm
, UVC's, checked all engine wiring, swapped injectors around to different holes, tried 4 different chips from Tony.... it still tan the same. I was about to install stock injectors back in the truck after 3 weeks of mucking around with it because I figured it was my injectors and it was a lost cause, but before I did that I called Jody at DP
to see what he thought. I had never done business with him, but thank god I made the call. He knew it was a tuning issue, and when I was describing the truck's symptoms to him, he was basically finishing my sentences, he knew exactly what had to be done with the tuning.
He sent me a chip with a few different tunes on it to try and see which ran the best and the second I plugged the chip in the truck ran MINT. I thought my truck was a lost cause with the stage 2's because of the way it idled and ran and romped and had the "on/off" pedal. Tuning fixed it. I had to go to DP
in order to get the right tuning.
