08 vette

how do you get an custom tune?

I finally got enough courage to install my new predator I've been doing research, reading post, u-tube etc. I've came to the conclusion that i am a big chicken.......... so i opened the door found the plug in thing and installed the tune ...........it was very easy but its hard to tell if it is much ...

wow i just got my new u7194 read the small manual now iam really scared 300.00 +- predator vs. 62,000.00 vette
