I would do some bolt on first before installing the Cobb AP3 so you can install the best OTS map available based on what you have installed. You will definitely feel a difference. Power is more linear depending on what tune you install. These are just revs while in park. While driving I see the torque hit 400+ Need dyno and tune to get the most out of FBO and see how much whp was gained.
Definitely
on Cobb AP3, support from Josh D. @ Cobb was outstanding.
The shift light is mainly for manual cars, it shows the driver the optimal time to shift with the light.
