Filled the car up with pump gas and drove about 30 miles. Stay out of the throttle and no detonation at 12.2 to 1. The hottest it got was 205 right off the highway. It will accelerate with traffic and up hills no detonation. It was BORING!!!!! But successful. I had to put a sign right in front of me saying “NO” so I wouldn’t hammer it! A kid in a honda kept poking me at a light, took all my self control to let him scamper away!
