I have 2 tunes. one on 94 octane @ 29psi and one on 91 octane @ 25psi (91 i use for the winter and long road trips where stations dont have 94)
Dont forget the compression ratio of the engine determines what psi is good for your car. Hence why most 370z's are only running ~5psi. If/when i build the engine ill probably put it up to 35psi..lol.
