Has anyone installed the predator with the performance tune. how did the tune feel afterwards. did the predator come with the performance tune allready on it.
Well, I have an '04 with nothing but a Bassani cat-back, and I didn't notice much at all with the performance tune that came on the predator. Maybe after a few more mods it will be more noticable, but I will be getting a custom tune soon.
I liked it as well. It disables your O2 sensors and also smoothed out my idle which was needed after the headers. I know you can do all this manually but Performance Tune worked for me until I got the pulley.
