Chip I'm starting to get this SV1 tuned in better! I went 111 and change in the 1/8th and went from 28 to 32s on the highs and I went 112.8mph on back to back passes and nothing else changed... 60s were even 1.44 each... It was a hair over 1.5mph pickup! I have lots more tuning left but only other time out was the Jensen mean street deal.
