Custom tune vs 91 on 93 oct tune
Posted: Sat Apr 22, 2017 11:54 pm
Got a question... Was just wondering... I run a 89 custom tune and was thinking if a can 91 tune running 93 octane would out perform it... Car is a Challenger 3.6 with CAI Magnaflows catch can and a ported throttle body... What do you guys a Diablosport think?
