Alright, I know it's a slug, but it looks real pretty and has enough room for the family and pulls the boat fine. I'm just sick of flooring it to keep up with everyone else on the road (I live in Miami). What will give me some immediate torque, that I will feel in lower rpms, program tune or is there something better? Besides a 6.0 or a supercharger.

I think I'm going to go with the tune first. Truck is still has a extended warranty on it so I'll wait to do anything inside the engine. Thanks for the input, except for all those 4.8l bashers, lol.

Thanks for the info. I guess I will start saving for the 6.0 and by the time I have the cash, my warranty will about up. I could work out to be perfect timing.

i honestly can't belive they would put 4.8's in crew cabs...there really is no way to make that truck get out of its own way, especially pulling something with a load full of people, without voiding the warranty....
if you dont want to do an engine swap, look into putting a front mount turbo on your 4.8, thats what im going to do. kb racing on here sells super nice looking complete kits for 2500. foose04 on here make 623rwhp give or take a few, on his turbo 4.8 @15psi with an ls6 cam/springs (which is about a 150 dollar cam package used)......definately something to look into
or you can build your own turbo kit
