Ok so I just got my invidia turboback installed on my 06 WRX and it's time to re-tune the car. I see that there are two different maps for 93 octane fuel: "Stage 2 93 MT v300.ptm" and "Stage 2 93 MT v102.ptm". In the notes they both say: "Stage 2 using 93 octane fuel. Requires stock turbo, stock intake or Cobb Tuning SF Intake, and turbo-back exhaust"
How do I determine what map to use? I have the intake and the turboback exhaust and I want to run 93 octane so those are the right maps but they seem the same to the untrained eye that I must have.
Are there better maps that can be downloaded? I know about pro tunes and that they're better. Eventually I'll get one but just not right now.
