I have been through 3 tanks of gas since I changed my 2004 LT to the 2.75 final drive gear ratio. I never use the BC to calculate my gas mileage. Dividing miles by gallons I am getting 3.5 miles per gallon better with the 2.75 ratio. It also has a little better acceleration feel on the throttle response. I now get the same gas mileage with my 2004 LT that I get with my 2000 LT. I'm getting 50 mpg now with the 10% Ethanol fuel with both of my LT's. :yeah:

I'm very easy on my LT's unless I'm being chased in the mountains.

What year did they change the ratios?

thanks...Randy

I gotta stir the pot though. How are you calculating your actual mileage ridden? Changing the ratio changes the total miles indicated. Just curious if you adjusted for that?

I thought the LT used the ABS ring for speedometer and odometer input...

And I'm gonna stir some too.....








Did that fix the tachometer issue?
I think the tach issue was on the Y2K if memory serves:think:

Changing FD ratio does not change wheel speed, different wheel circumference would affect speedometer

And who needs a tach anyways
