ya i kno.. 4.8's are a bitch on the top end arent they, lol jk. What rpm/mph are you shifting at in your 2-3 shift?

im not exactly sure...either 5800 or 6000...i know first shifs out at 6000. the mph on 2-3 is at 80-85

with my hypercrapper mine used to shift out at 90ish. i had the rev limiter set at 6200 and it would do 95 and then hit the limiter. and it actually pulled all the way up there.
but i have 3.42's with 255/70/16s. weenie tires. haha.
i heard some stuff bout a turbo on one of them LS2 SSR's said it turned some really impressive numbers. ill have to find where i read it.

damn tx, your tune may be a little wrong???? mines shifts 2-3 @94-95mph @ WOT ~6000rpm, and when I manually shift by myself I shift @~6100-6200 and it is @ 97-98mph!!! shift 1-2 is about 5900-6000rpm... by the way like you said my 2-3shift hits real strong but does not seem to be strong after the shift??? I do have 3.42's though....

i dont know if it matters or not but my brother did a 87octane tune on his and it kind shifts exactly like yours (mph), I dont know if it has to be because of him having 87tune and me having 93tune???

A set of 4.10's will wake up that 3rd gear some although I know some people will argue with me about that. The biggest improvement I noticed from the 3.73 to the 4.10 switch was after 70mph.

Mr. Sandog

I won't argue with you, but my experience was that by far the biggest difference going from 3.73's to 4.10's was 0-60 MPH. After that, the 3.73's had the advantage (IMO).

I went from 3:42's to 4:10's and I wish there was something in the 4:30 range. I would have gone that rout. But then the 4.8 has NO torque and lots of RPM so steep gears make big differences.

thats because i have 3.73 and you have 3.42. differences in tire sizes can make a difference too. mine used to switch out around 95 before the gears.

i would go 4.10 but 95% of my driving is freeway. i wanted 3.90's but i think 3.73 is a good all round gear too.

anyone have an opinion if they think the headers will help out my top end enough to hold off that ssr?

so maybe my brother has 3.73's in his truck??? does anyone know how to tell what gears a truck has with the VIN#???
