A Note:
Regarding fuel--the stock Mag tune used 91 Octane fuel to prevent/reduce detonation.

If you use 87, you have to make sure your tune is changed. I personally stay away from anything but 91 Octane with forced induction. Cheap insurance as far as I am concerned.

I have seen guys blow these big bitches up and they are not happy when they leave the vehicle. In all cases so far, they either beat the **** out of their engine or had a fuel related failure, like a fuel pump and then continued to run their engines while it knocked.
