How much engine mods can be done with a programmed track key? I intend on extracting more power from my boss in the near future. Just wondering if anyone has done a cai kit or complete exhaust or both with the track key tune?

 

The way I understand it is the track key is a ECU tune designed to boost stock configuration performance a bit. It is not designed to work in conjunction with aftermarket parts. I think you would be better off getting a aftermarket tune to go with your aftermarket parts...the car will be happier and so will you with the gains received.
