You know what's interesting is that I made 570 wheel on 2 gallons of e85 plus full tank 91 compared to this dyno session where I had 50/50 mix of MS109 and 91. I hear the best thing to do is run straight race gas (no crappy 91 at all) for best results but that's rather expensive.

Don't know if you have any e85 near you but even on a NA car a small e85 mix with pump should improve the octane and provide cooler burn (less knock) than pure pump gas.
