5.3 perfomance upgrades?????
I bought a 2001 silverado 1500 Z71 last year and its been good to me so far but i am looking to get more power out of it. It has true duals with cats only but thats it. What are some mods that i could do to get make it faster and more powerful other than a supercharger or engine swap. Are there cam, intake, programmers, air intakes, or anything else that my truck would really benefit from??? Any help is greatly appreciated!!!!
