[QUOTE="01bluesnake, post: 12265396, member: 84985"] A lot of good info in this thread. Yes, not tuning for race gas will not help as the burn rate does slow much more than 93. Depending how the tune is set up, the car may be able to take advantage of a higher octane fuel and add more timing thus getting some more power. If the timing in the tune is only allowed to go as high as it was tuned regardless of knock, it will not be any benefit running a high octane fuel and can actually hurt more than help. Also the tire pressure seems very low and can cause wondering up top and slow ET as mentioned from increased rolling resistance. Think of driving on a flat vs a tire with air, the lower the harder it is to move. I recommend getting the car on a two step at the line, and increase tire pressure. You want to go as high as possible without hurting your '60. [/QUOTE]
