ECU tuning in MD

when you guys are getting tuned do you run 93 or stay with 89? I just ask bc i think i remember the gen 1s call for 89octane and i havent bought a gen2 yet and dont know whats required for them.

I use the 93 but some guys say that the 89 is better... I would say tune with what your gonna use all the time.
