I am thinking about this for performance.

Either Dinan exhaust, stage 3 chip and throttle body and CAI. $$$ 300ish hp

The other option is save a ton of dollars and get the powerchips and have about the same horse power. I am comfortable with Dinan and dont know that much about powerchips. Powerchips for the M62 4.4i is only $640.00. 300ish hp.
