Its a rear end code.

That is the code for the 3.08 rear ratio. While it keeps your fuel economy high, it doesn't give you that "grunt" on takeoff. At 80 mph, I am only pushing 1700 rpm in 6th.

Look at the RPO sheet in your glove box. GU4 is the code for 3.08 gears. GU6 is 3.42 gears.
A tired motor, sticky oversized wheels and tires and those big diameter exhaust systems can all contribute to low torque output.

My rear end was rebuilt a month ago as well. The spider gears stripped. The carrier and everything in it is new i believe.

When the rear was rebuilt, did they change the ring and pinion gears by chance? Did you notice anything different in the way it drove after the repair?
Another post here reminded me of a car we used to have. It had Eagle GT tires on it and you could punch the gas at 45mph and the car would go sideways, spinning the tires. Once we switched over to BFG Radial T/As that all stopped and the car just plain hooked up and ran.
I reckon with a 3.73 gear that your rig has a 4-speed. Are those tires/wheels taller than stock, have much more roll out?
