I hope this is the right spot to post this, sorry if not. I bought a 2005 8 MR that was tuned by RoadRace and has a Hallman MBC. My question is, can I just turn the boost up and down and be safe and run good? Or would I need to retune if I decided to increase/decrease the boost via the MBC knob. I really can't locate an answer on this. I hear some yes and some no on the matter and wondered if anyone had a definite answer!
