PM sent on race gas.
If you want to keep using the 93 cai tune then get some unleded vp109 or sunoco 104 octane race gas and do a 50/50 mix with 93 gas and you will hit the 12.90s easy. If you only want to run the 93 gas then go to the 91 cai tune it will run a lot better.
I posted them in the track talk section under the thread called the same thing as this one. I raced at San Antonio Raceway. They said that since there werent very many people there that night they were having trouble keeping the track at race temps. Maybe thats why I was having so much trouble with traction.
