Yeah, I am tuned by HPA, and their tune does do a pretty good job advancing timing with fuels. It's not a true flex fuel tune by any stretch but it's well designed to give you the added power with better fuel.And you're tuned by HPA, right? I think their tune adjusts for fuel quality automatically from what I recall. I would be running Petro 94 here, I don't think you guys get that out west (we don't get Shell 93 here).
I get Petro 94 when I am at Area 27 (they have pumps with it at the track!) and it definitely performs much better. However, I usually mix whatever gas I have with MS109 at the track for the best possible knock resistance.
