The Stage 2 Twin Turbo Cam is the one you want to go with when you have a 6.0 or a 6.2 with 58-65mm turbos. Idle will be relatively mild, but more aggressive than stock. This is a cam that is just as comfortable delivering you to work as it is pushing you down the 1320 and turning on that win light.
