"custom" tune using EFI live vs. bb tune

since tune shit is already here:

If I get BB to tune me for 91+ fuel this weekend, do I need 91 in the tank already? Common sense would tell me yes, but I want a good confirmation. I just filled up today not thinking about it.

Yes, you should have it in your tank. At the very least, Justin can tell you if your gas is good quality or not.
 
Thanks Jenna, my commons sense told me after I filled up that I would need it, and it was a little too late, is there an issue with running RXP to boost the octane? I keep screwing this up. Before long I will just have to move out near you guys...
