Trying....
So here it goes guys I know you probly get tired of answering these dumb questions. But I just bought a 2013 SHO black on black and I love it but I need more power coming from a 600 HP CTS v. So I need in detail how to get mid 12.5 in the quarter. Like exactly what I need. I'm looking at livernoise tune to start. But if you guys can pass on good info on exactly what I need like links to the items that would be much appreciated. Thanks a bunch fellas. Oh an one more thing I see you can get like some parts cheap in deferent spots like 1aauto so if I could get a 3 bar map sensor from them and t stat to save money that would be awesome.
