I have a 2006 GMC Sierra 5.3l V8. I have put on a cold air intake, a cap back exhaust system and a superchip. I am thinking about putting on a 'Magnacharger' s/c. It will cost me about $7300 all said and done and I am wondering if there is something better I could do for that price to give me some good power?

 

idk about the gm trucks but the supercharger on a 5.7 tundra is definatly worth the money. alot of guys have been throwing them on for towing upgrades and the track guys are running high 12s with them. id have one but i dont have 6k to drop.
