After running the stock tune against the Diablo tune on the dyno and seeing virtually no difference I was anxious to track test it. Last Fri nite I had the chance and made 4 passes with the Diablo tune in it. All runs were from 12.91 to 13.00. I loaded the stock tune back in and made two passes and went 13.26 and 13.36 with a loss of 2 or 3 mph. Loaded the Diablo tune back in and went back to back 13.00.

I am happy with 2 to 3 tenth gains and look forward to the fall weather and hopefully hitting 12.70'.
