Anyone know of a good brand of octane booster that actually works? I am running close to 10.1 compression and I think the gas here in New Mihico sucks. Best I can get it 91 octane. I have a detonation issue at 60-75 mph when I put the gas pedal to the floor. Doesn't have issues at low speed. I'm not sure if it may be a timing issue or not but thought this would be an easy fix if it's just the gas. Car seems to run fine and I'm not advance a hole bunch. what do you guys think would be a good initial advance? I think I am only running about 10 degrees initial due to detonation beyond that. Could this also be a gas grade issue?
