I have a 2004 chevy silverado ext cab with the 5.3L. im trying to get more power out of it but im not sure where to start. as of now it has a K&N filter and exhaust. I've been told i can do a intake and throttle body swap but to what? anything will help thanks.

04Chevy,
The 5.3 is a very potent engine with plenty of upgrades available. A new cold air intake would help, along with a throttle body swap. Your biggest gains would be from switching the stock exhaust manifolds out for some long-tube header that would match up to your existing exhaust. Other than that, you should look into having a custom tune written for your truck on the dyno, which will not only help with power but your transmission as well.
If you have any other questions, let us know!
