What they said. That's a bunch of weight (I know, I tow 16,500 with my 350). Mod's to my truck are:
Air-Raid cold air input, Garret GTP38R Ball Bearing turbo, AFE intake, CRX Intercooler pipes, RiffRaff Boots, Billet Plenums, 160/30 Full-Force Injectors, Banks Monster Turbo-Back 4 inch, PHP Hydra running a 25 hp tune (that's a bit hot under load - I have to watch EGT's) and I push it through a dual disk south bend organic clutch.
There's other mods to the truck (like air bags and camera's), but from a power point - it gets the job done. It doesn't keep up with the new ones, but it gets there reliably.
If I do anything more, I'll have to tear into the bottom half I am sure and I just don't want to do that.
