also, how much horsepower do you have now? how much you want? this is still a truck too, so without a major engine build, you may hit a limit on power.

you can do all kinds of bolt on's and it wont make that much difference. it is a truck and will really never be fast. if you want power then you have to do somthing major like maxx said. it looks like you have done most of the add on things. you can still do hi flow cat's, corvette servo in the trans, after market mass air flow sensor. and get a custom pcm.

put you some sort of headers on there with the high flow cats and a new mass air flow..it'll open it up a lot more than the stocks are doing now

Has anyone put headers on a 5.3L? It looks like the stock manifold already kinda looks like headers. I have herd that headers on the 5.3 don't do much. A friend on mine put some on and said he noticed no chnage? They cost alot more than the ones for a 350 also.

my friend put long tube pacesetters on his with a tune and intake and took it to the track and ran a 15 flat..my other friend with a stock 5.3 ran a 16.3 so those three mods took a second or so off his time

shot of nitrous is do all you want. a 5.3L will handle a 120 wet shot. my truck dyno 392 at the wheels and it has the basics
