What kind of power gain am I looking at with an upgraded throttle body and ported int I currently have a K&N intake with SLP Headers and a full SLP Loudmouth exhaust on my 2004 GTO I am looking into porting the intake and putting in a 90mm throttle body to increase air flow. After that is done and I get the car Dyno tuned what kind of power gain will I be looking at?
Thanks
