Just bought a 2010 Silverado crew cab 4wd, 5.3l, 6l80e and im looking to squeeze some power out of it (gas mileage too)

Im looking for CAI, SS LT headers, Programmer, UD pulley, TB etc. Im not super familiar with the trucks as ive had my camaro for a good 4 years now so if you have other suggestions or candidates post em up. nothing major like nitrous or FI, ive got a money pit as a result of that already If you have a stall converter laying around id entertain the idea.

also, what are the different free mods for the trucks?

Im in houston tx, 77008

 

dont do any programmers get a tune.... cai long tubes and tune will get u to ur goal it sounds like....add a TC to get it to the ground quicker and i think u'd be happy

 

programmer is almost as good but cheaper, but im sure in the end ill end up with a tune. Im also keeping the factory warranty so ill have to always keep a way around that.
