RE: changing tunes/octane ratings
Sorry for thelate reply... the 87 tune was noticable over stock tune. 91 vs 87 perf tune not noticable, I'll try the 91 torque on this tank but I'm sure I'll go back to the 87 perf. for daily driving.

So, how's the 87 tune with the manual? Huh? Huh? Huh?

I just got my X-Cal and loaded the 87 tune and want to experiment with the 91 tunes. My question is do I change the tune before I fill up with91 or after, and how soon before or after?
