2V, 03' GT. I know that there will not be huge gains, so I am ok with the minimal HP gains. It will never be a race car and there will always be someone faster. I am old school and like the sound. Not a big fan of forced injection. Not having to replace the springs is a plus and why I want to stay with the stage 1. Still gives me all around power throughout the power band. The car is sniper tuned so I assume it will need to be tuned. Will be doing all the other bolt ons also. Just looking to have a fun car to drive.
