Default Power mods for 04' 5.3 LM7

The truck has the cats cut with straight exhaust no mufflers 2 1/4" piping,Volant CAI,and custom tune. Whats the next step i should take for adding more power? I'm thinking about F/I but if i go that route id like it to be a root style charger and looking at the prices on those new/used doesn't really seem to be in my price range which is around the $1000-$1500. and suggestions?

Lol are you serious? You never lower a lifted truck that's against southern law lol. I'm not tryin to run 10's in the 1/4 mile I'm jus lookin for some more power and torque. My truck is already faster than any stock f150 or stock z71 I've ran against the gears make up for the tires.
