I have a 2010 Charger SXT with the 3.5HO and I was running 93 tune with 93 oct and was told i was wasting fuel and hurting my motor to drop it to 89 oct and 89 tune is there any truth to this? And what is a good throttle boost to set it at for the V6 charger?

anyone that tells you running the best possible, highest octane fuel is hurting your motor, likely drives a prius and has no ability to comprehend what it is we do and why you bought this tuner in the first place

Sorry....easy answer, no, 93 is not hurting anything

I have the tuner and a CAI and ported throttle body and duel exhaust. In the setting on my predator should I add any fuel?
