before I professional tuned mine I bought a Granitelli Diablo tuner/ added a K&N intake ....plugged in the tuner, pushed a few buttons and instantly more throttle response.
also later added catback exhaust - borla headers - MAF sensor - 160 degree thermostat. Then sent out the unit for proffessionl tuning.
Now all that AND push the factory supercharger button and woooooah - off we go -------
Oh yeah - added a back up camera so I can watch how fast I go by sh*t
