just got 4.10's installed cars not accelerating like its suppose to 
"M6" well ive just got my 4.10's installed and ive broke them in i have never got them calibrated but besides that it says im going faster than what im doing but im wondering why isnt the car accelerating like its suppose, to the engine revs hard and it tachs up quick but the acceleration isnt there with it but when my 3.42's were in there it was fine.. is it just because the cars not calibrated yet?

Because of the lower gearing out back, it'll make each gear of the tranny seem much shorter, so you'll have to shift more often. It may not "feel" faster to you, but try running at the track ... it's faster 
.
Funny, you're probably the first person who's ever said 3.42's feel faster than 4.10's!?

I got a wicked deal on the 9" and the 4.56's were already in it. It's definitely too much gear for 26" tires on the track, but for the street it's perfect. I'm turning 200rpm LESS at 70mph with the T56/4.56 combo that I was with the 4l60e/3.23's.
