So I got my truck back from 4wheelparts after I had 4.56's installed. Drove It nice and easy for a few hundred miles... Opened her up the other nite and actually spun the tires pretty well with 33s! I used to not even be able to do that with stock tires!

Anyway, with the edge cs set to level 2 and timing bumped 1 degree with 91 octane, i did 0-60 in 7.5!!! Last time I tried, my truck was all stock in trans mode only and ran 8.9 to 60...

It honestly feels faster now with the gears and 33s on level 2, but damn! 1.4 seconds faster?!? and yes it IS calibrated for 4.56's and 305/55/20's...

I dunno, im pretty impressed with those numbers... Even if they may be a little optimistic I thought I would share. Oh and heres a pic for what its worth.

 

Damn makes me wanna get gears haha 35s with 373's is painful

 

Ha! Ya I thought 33s without gears was torture... Dunno how u guys do it with the 35's!?!

 

i like where you have it placed lol

 

There is no replacement for gears!
Since the 4.56 swap in our suburban, it has turned into a monster. I think that the hitch would break before she stopped pulling.

 

Lol, Ya I had the pod they sell but I couldn't match the silver color... Looked like *** so I hid it in there. Fit perfect and looks clean

 

If 0-60 times are important to you, ask yourself if a truck is the right choice.

 

^^ trucks arent just for hauling stuff big dog...

 

I've got 4.10s and had 245/70R17s and was knocking off 7.8-8.0 0-60s pretty regularly. Gears make a huge difference! That was on level 2 with 88octance.

 

mine pulls high 6s on 35s and 3.73

getting 4.56 installed hopefully this week
