RE: V6 3.9L acceleration?
if im not mistaken, these v6's do need an adequate amount of back pressure to keep their low end torque, i still have my cat on and i still have a decent amount of power in the low range, torque gets you rolling... i do agree with the 3.55 gears, but would that be common on a 4x4 to have such a small gear ratio?

i think the 31's are killing you. i noticed a huge difference when i out mine on. i think about 0-30 is sluggish, and then it sorta kicks in a bit and you can feel the power switch (still in first gear) I'll see if i can do a test tomorrow cause it sounds like i have a pretty well identical truck to you.

dude you have a heavy 4x4 with a v6 and 31 inch tires, it's not going to be fast, removing the cat wont help you either, it causes a loss of low end in the 3.9. you might want to replace your o2 sensors with ngk o2's. that will make sure the computer is reading everything right giving you better air fuel ratios.

idk my truck is like a frick'n rocket off the line w/ the pedal on the floor, idk what my time is i really dont have anyplace level to test for it, and no tracks locally but id say that is a little slow, and i think my cat is gone, as in the guy who owned it b4 me nocked it out and stuck the pipe for it back in,
