If you already had a full exhaust and added G3's..

In my opinion as well as others, I would get the car tuned after installing G3 intakes. When I had my car tuned, the stock tune with G3s would run leaner than I am comfortable with and there was also some detonation which is something others have experienced as well.

After the tune, my A/F ratio was nice and safe across the board, the car ran smoother and I picked up another 5whp.
