Mine seem kind of low to me. These are at 6K and I'm wondering if they are normal.
1st gear (spinnin like a ****)
2nd 60-65 (spinnin)
3rd 85
4th 115

And at 80mph I'm at 2150 RPM's. I looked it up on F-body.org/gears and mine are off from what that says. And I'm sure my PCM is calibrated for 3.73's. Are these the normal shift points?

 

They do seem a little low, from my calculations. What is the diameter of the tires you are running? That could be the difference.

 

stock size 245/50/16's. And the clutch definatly isn't slipping, I get more than a chirp going into 3rd...

 

I changed my shift points and i dropped like 1 tenth.
1st 5400
2nd 5700

 

It helped me get a little more traction and on 3rd gear (6000). I accidentally pressed enter so i put 2 separate posts.

 

What I mean is what MPH are you guys at when you are at 6K in each gear.

 

Using a 25.5" tall tire, I came up with the following speeds @ 6k:

1st - 46
2nd - 69
3rd - 94
4th - 122
5th - 165
6th - 244 (if you could overcome the drag and the jump to .5 o/d)

A shorter tire will lower these numbers, but I think your tires are pretty close.

You may also want to check the accuracy of the speedo against the mile markers on the freeway, to see if it's off. Even though you may have recalibrated the ECM, it could be off a bit.

 

I think alot of it might be speedo lag. I ran it up to 6K in 3rd and pushed in the clutch and the speedo kept pulling and stopped at 91. And i heard the stock tachs might be off by a couple hundred rpms....

 

My tach is about 200 rpms off - forget which way though

 

That sounds about right, what I about see with my 3.73's.

And makes jives with what I used to see with 3.42's. (numbers being about 9% higher (since 3.42's are about 9% longer than 3.73's)
