I did some math, (or FBODY gears calc did) and it says this

1900 rpm in 4th gear with 2.73 gear and EDIT< 255/30/22 >

equals

86 MPH


Im doing

Stock tire is 225/75/15

Its only a 2mph difference between the two.

I know one thing I dang on sure wasnt anywhere near 55 mph.

I know its slipping but this bad

Any idea how much MPG im loosing? Think I can get atleast 16 with a good tranny?

You are deff slipping, you should be doing at least 82-85 MPH at that rpm on 4th gear.

How do you like that programming software? I have read a lot about it, I almost bought it for my 454SS truck, never got around to try it though.

Time for a new trans.

I love the EBL, best thing ever. If you are troubleshooting this thing helps out alot, since Im not HI PO (YET) im just getting used to it.

But the ablity to do what ever you want is the best. (granted im still learing how to do that, I STILL LOVE IT)

Best $400 ive ever spent.

BTW EBL is Hardware/software too.
