i dont know if this is were i sould be asking but i have a 2004 z 71 5.3 and it has 4.10 gears but what should i do for sum cheep noticable power and gas gains the truck also has 33" tires

 

Welcome! You can ask here but you might want to post down in the GM engine threads. If you don't have a cold air intake and exhaust, thats pretty much a standard starting point. You might even be able to find them used down in the parts classified section....

 

i do have a 2 chamber dumped i had a 1 chamber but i drove alot of highway so i got the 2 chamber what kind do u have what is the best that is a flowmaster

 

Welcome, agreed, a cai and free flowing exhaust would help, especially longtube headers, I run a cai from autozone, a spectre kit, many people stray because its not kn or volant, but in my opinion, a tube is a tube. Also check into a custom tune for your truck after u dd some more bolt on's, they and you, will benefit more from it. Personally I like Flowmasters, i have a 40 series on my truck and love it. Good Luck, Chris

 

Agreed on the above.... If you are just looking for a little boost in power then a basic CAI will do just fine. As far as mufflers, its personal preference, I used to run flowmasters but I prefer magnaflows now. Just remember with a tune, most of the time you have to run premium fuel after. If you don't wanna spend the money on the fuel, steer clear of a tune. Oh...there are 87 octane tunes, but they really don't give you much for you money, just FYI....
