Performance on a 03 silverado
ok i just recently bought a 02 chevy with the 5.3 and flowmaster mufflers on it. i was wondering what the best preformance upgrade would be for the money and how much power it would give me. thinking about an intake and chip or custon tune. any suggestions?

i got my predator on ebay for $150 shipped. and before people bash the handhelds, this holds a handful of tunes and you can get free custome tunes from diablo (or at least you could)
