Definitely get that tune done as soon as you can. I prefer the AP for all the extra features that come standard on it.

Best way to protect these motors is with a custom tune where the timing is jacked way down. Period. The catch 22 here is that timing is also where you can make a lot of power on these cars. I run high boost, 10.8:1 AFRs and low timing. I have the environmental variables configured to protect my motor. My suggestion for those wanting to protect their motors is to get tuned on 91 octane and ...
