I have a 2017 Challenger rt 5.7 that?s supercharged. I downloaded the tune file. I will be changing out heads, headers, cam, forged internals, phaser limiter, push rods, injectors, and to hell cat lifters. If I follow the HP Tuners beginners book for my car, it lists changes as separate tuning events. Like heads and cam or supercharger or what have you. Do I just work in all these sections at the same time. The part I am concerned about is the cam and the injectors. Also will be pumping up boost to hopefully 20#?s with my P1X. Little overwhelmed. I?m comfortable with engine work, but a lot of tuning changes at one time. Any help is greatly appreciated. Just point me in the right direction.
