Hi! New guy here. I have 2018 Tahoe L86 6.2 Premier with 8L90. Recently I've installed GPI Stage 1 high lift cam and all the supporting mods. Car runs perfectly, I made some tweaks in a tune so when the car changes gears, engine won't shut off because of low rpm for a new Cam. The problem is... Sometimes on a bumpy roads or while going over big obstacles, car still shuts off randomly when going to hard from side to side. I don't know why this can happen, any ideas?
