so i'm curious... to those of you with sti, or evo or 335i or whatever the case is, when you order your off the shelf tune can any of you guys even ran anything other than the 91 tune with our local pump gas? i'm basically making this thread because i'm thinking about building a 335i and our gas is reeally putting a damper on it (not a race car, want to run pump only). the cobb stage 2 aggressive isa 93 octane tune with bolt ons and it's apparently really good and then the map 2 in the jb4 would be comparable but it's also a 93 octane tune and it sounds like our 94 octane would get knock on those tunes. on top of that, i'm not even sure any of our gas would run any good using a 91 tune either.
