Best Hp For The Money

What is the best way to gain hp in my 5.7L sierra without spending a lot of money?

a custom pcm tune is probly your best bang for the buck. do u have anything done to your truck? if so you can have them tune your pcm to match them and get the most out of them. Wester's and Nelsons are pretty much the same, nelson learned from westers, but theres also wait4meperformance.com that has a tune for about a 1/3 the cost of the other 2.

I'm a big fan of the cold air intakes and cat back exhaust system upgrades. These are the few things u can do that actually gain u both HP and MPG!! :evillol:
