Yes I understand and is why I stated you both adjust other parameters.
I really appreciate you taking the time to once again explain how and why you tune the way you do.
Only three more questions:
1.) Does your tune keep the turbo's speed within the maximum specified rpm by the OEM?
Yes I do.
Believe it or not even 28psi at 3000rpm does not overspin the turbos. Peak shaft speed happens at HIGH RPM not low RPM. If you plot shaft speed of a turbo the curve will look similar to plotting Maf g/s on the same run. This is where data comes in to play.
2.) If I purchased a 93 octane tune from you, went 4 wheeling in another state the didn't have 93 octane my choices would be to A.) Remove the tune or B.) Purchase another tune like maybe 91. Correct?
You can simply run a 91oct Off the shelf map that COBB provides, or even run their 87oct map, both of which are free when you purchase a COBB Accessport. No need to purchase another map.
Although it might be smarter to purchase an alternative 87 octane that way one could run a 87 octane tune on 91 octane.
- This would be the right (and SAFE) thing to do.
3.) How long would it take to remove tune or change to another tune?
- 1-2 minutes. The Accessport flashes very quick!
I'm guessing if I was running a 93 octane tune and wanted to change it to a 87 octane tune that I'd have to first remove the 93 octane tune reverting back to stock and then install the 87 octane tune?
- You would not need to remove the tune, you can simply change maps without reverting back to stock. This also takes 1-2 minutes.
