I have taken repeated stabs at my gen 4 silverado and need some a real tuner! When the DOD went out I installed a comp cams stage 1 thumper (drop in cam). in addition to removing the dod I also opted for the non vvt version and replaced the timing cover and so forth. No additional modification's.
* Idle is rough and bounces between advance
* Surge causes rough braking at times/difficult in icy parking lots
* Not very responsive on low end
* Transmission shift characteristics are close but not perfect
* Randomly will throw a P0157 stuck lean code. Will go for weeks after reset.
Any thoughts or comments are appreciated. 1122022 log.hpl2022 new years tune.hpt
