We have 100 octane "race gas" in Brentwood, 10 minutes away from my office. If it was illegal, why would they sell it. Definitely not illegal. I don't think 76 sells "illegal gas"

I follow pg's posts for a while. Only 22hp gain and only 8 ft/lbs of torque from pg's aa tune. I think thats modest esp because other tuners say they get 40hp. Maybe you mean its way out of line because its too low? I looked and saw that King Tut got 20hp gain and also 8 ft/lbs of torque from his aa tune, basically identical to pg. So at least King Tut was able to duplicate it. So what was wrong with pg's results? I am thinking of going the same route as pg so i'm curious about this.

Also curious if you download pg's dyno files to see if anything was wrong?

I think even a 20hp gain from switching to a higher octane is reason enough to put it in your car. Hands down.
