15.0 mpg to 21.6 mpg!

Following up on the thread. Turns out the gears are 3.23. Which I kept. The TrueTrac is now in the car and I'm picking it up tomorrow. Looking forward to ... T R A C T I O N !

7miles out, Are you saying that during this entire thread that you thought/assumed/believed that you had a 3.55 ring and pinion installed but you were mistaken and you really have had a 3.23 all along? Just trying to understand all of this.
