After installing a CAI and aftermarket exhaust do you get the full power gains or do you need to do any retuning of the car to maximize the power with these upgrades?

 

the biggest thing you need to do is pull the negative power cable for about 5 minutes or so, then the ecu will reset and re-learn how to function with the increased flow. Make sure you have your radio code (if it's stock) before you do this.
