Hello everyone I just got a new 2018 ZL1 and never owning a boosted car or modifying one I need a little help on what I should do. for the mods I'm going to keep it simple I was thinking, 2" Headers with 3" exhaust no Cats, CAI, tune, and pulley upgrade.(I'm wanting 15psi or more safely) the part I need help with is the Pulley what kind of pulley would you guys with ZL1's recommend with these mods and if it was on a stock car. will switching a pully throw a check engine code? Thanks for the help!
