Hello I just bought a 2001 5.3l Chevy. I live in Texas and always been interested in ls engines. Its all stock and I need some ideas to give my truck more power. Thanks for your help.

 

well there are lots of mods what is your budget and what do u use your truck for ? do you want 1/4 mile ? or towing power ? most will tell you a basic tune from are sponsors and lt headers. drp in k&n filter is a good place to start . next u can stall converter ,cam and gears, then retune. end less posibiltys lol
