just checking in/need some help

I am just checking in. I am new to the LS world and need some help. I have a 2003 GMC Sierra SLT Quadrasteer 4X4 with a 5.3L. I have the hypertech III power programmer and I just ordered a CAI and I am adding a flowmaster. I am looking for the stock specs on my motor and what are the cheapest and easist bolt on upgrades I can do. What LS motors can I use parts off of to save money? That kind of stuff. All help will be greatly appreciated. I will be adding photos as soon as I can. I hope to here form you guys.

LS is LS, drop the Crapertech and get a custom tune. stay away from tne Flow...get you a Magnaflow or Borla....

Welcome Jamie! +1 on dropping the handheld tuner. Get a Nelson tune...you won't regret it!

Welcome, Lose the hand held and get the nelson tune,magnaflow and go ahead and get some lts while your at it, it will be worth it

Welcome to ls1truck! Get a tune. If you want to change exhaust get some long tubes while your at it. I like my borla mufflers.

Welcome to the site.

Guys... :nono: There is nothing wrong with a Flow. I have had them on every truck I have owned and they are great. But Magnaflow and Borla ARE good alternatives...

Cheap and easy for your truck:
