ok i have a 2007 silverado classic with the vortec max. im new to the site and i think this is where i ask questions about this truck. but anyways the only tihn i have is dual exhaust with glass packs, a k and n set up, and an airraid throttle body spacer. this truck runs great even with 35's, but i just wanna see what more i can get out of it with a tune. whats the best tune out there for my truck? thanx guys!
