Its probably a factory computer setting to get by the EPA requirments. Both my 01-06 are weak on power. My firend has a 5.3L and is big on chevy and always talks about upgrading to a power chip so that might be your only solution.

I had a '99 w5.3 3.42 RR , Installed a cold air intake, trottle body spacer (which is suppose to really help on low end). and 3" performance exhaust. It really made alot of diffence!

Get a predator programmer or a custom tune to reduce the Torque Management. This will give you plenty of torque and save some gas as you won't have to floor it to take off anymore.

Check to see if your truck has the G80 Locking Rear-end option, if you do then it will take a tremendous power increase to spin them rear tires.
