im wanting more power out of my half ton, i have true duals from the converters and a tb spacer im looking for some advice on some more motor work, i was thinkin about an ls intake and tb but is there a better route, any information would be helpful. i have an 04 half ton silverado 4x4 with the 5.3, would a bully dog be sufficient and help me also if i do a tb and intake how do i go about telling the computer, can i do that through a bully dog

 

I recommend you do a lot more reading on this site and figure out what your goals are with your truck. My personal recommendation would be to get rid of the true duals and the TB spacer, get you a set of calspeed LT headers and bolt a decent exhaust to those, a cold air intake(one from autozone), and a live tune or at least a good mail order tune from one of the sponsors on the right. Best advice is to figure out your budget and your goals and then do a LOT of research on here and other websites. Ask a lot of questions and try out some things and see what you like. Good luck with your power quest.

 

Throw the spacer in the garbage. They don't work the advice above is the best you can get.

 

It is because your goals seem vague. Everyone has different goals and a different budget to work with.

The norm to start out with is a cold air intake system, long tube headers, good free flowing exhaust and a good tune from a reputable tuner.

Next would be a tbss/nnbs intake, underdrive pulley, posi, gears, cam, stall.

The more you read on here, the more educated product sized and selections you will be able to make....its not a matter of just throwing any parts on and seeing where the chips fall....weve all had to read and research alot. if you had a specific goal and budget to play with, itd be easier to help you though.

Good luck with your project and feel free to pm any questions....
