hey i managed a 14.8 at 90ish with a 3000TT yank and 4.10s in a 2001 ext cab 4.8.. so you got some catching up to do... on small tires though...

Your gonna see a big difference. i had them in my last truck (wreck) and it would get up quicker than my current truck and it has 50 more horses!
It will also give you more towing power. Did you check your shift points?

fat girl, 10 speed....yep good analogy. had the gears installed yesterday and the diff is insane! i need to have the tune changed for the gears though seem my speedo is reading about 70mph when im doin 50 by the GPS. but 21-2150 rpm at 65 mph is pretty damn nice. no more downshiftin on hills. i think ill wait for the weather to cool down before tryin it at the track again though. the wheels are 20's. the truck needs a drop BAD was thinkin a 2/4
