New Gears.... now what???
I posted another thread on swapping my 3.23 gears for 4.10 on my RWD 2005 GMC Sierra 1500 with the 5.3L and 4 speed auto (4L60e). I took the truck in this morning and picked it up about 2 hours ago...

I have a 97 1500 4wd with 4:56 gears, and the tuner will fix the problem easily. I used a Superchips Max Micro Tuner.
Have you had it on a dyno? I'm curious what kind of HP and torque increases you got with the tune.
I have never had it on a Dyno, but with the tune installed, it will light the tires up as long as I keep my foot on the gas, and without it it barely spins the tires.
Now, the 97 5.7 liter in my truck has 255hp@4600 rpm/330lb-ft@2800 rpm.
A pig for a 350 cu in motor.
My 5.3L is a hair over 300HP before the gears. Not sure on the torque but I believe it was under 300 with the 3.23 gears.
