i have a 4.8 silverado . all i have done is a hypertech power programmer . and i just cut the muffler off which aint that great by the way... what im looking for is a little bit more power with out spending a fortune. also it is my daily driver so something that would run well... any advice?

Welcome to the forum.
You're not going to like this but I suggest you dump the HPP3 and get a custom tune. The muffler really doesn't rob any power, at least not at your level of mods. Stick around and read all of the posts in the new member section, there's tons of info here.

Welcome. I second trever: get a custom tune. You'll see way more gains than with the Hpp3.

Welcome to the site!

Ditch that hand held for sure and go with the custom tune. Get yourself a cat back or put a free flowing muffler on there, longtubes, CAI or mod your stock intake.
