Gen4 needs a pro

[nwglobetrotter]

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

I'll be glad to build a tune for you.

Feel free to email me if you're interested.

Thanks,

Kevin has my truck running great, good dude to work with and very reasonably priced. Do yourself a favor, and get in contact with him.

Looks very rich and could use a little more idle timing to get you started.
