Afer I install the KB, I want to run 17psi for the street, and instead of just getting a more aggressive tune I want to run 19-20psi for the strip. Now how do I have the tune done? DO I just fill it up w 100 octane and do both tunes on that and just swap pulleys in between, or will the 17psi tune be affected a little because of better gas. Do I do them seperate 17psi on 93 octane, and 19+psi on 100 octane or better? How does Sutton usually do this? If any of you guys run a combo simular to what Im talking about?
