Correction Jeff, you forgot about me

. I now run 3.29 gears.
Jon, having run the stock 2.93 for a couple of years, 3.69 for about two years, and now 3.29 for the majority of this year, I can definitely say that 3.69 was by far the most fun. FWIW, my mileage dropped 12% going from the 2.93s to the 3.69s, and that also included the MP112 (versus the M90) and a cam. I wish I could have kept the 3.69s, but I had to go to 3.29 for trap speed reasons. I was reving at 5900 at the end of the 1/4 (roughly 123 MPH) and I wanted more room for my new setup. Until recently, I too used a TCC-300.
I have no clue how my mileage was affected going from 3.69 to 3.29 as I stopped checking a long time ago, but it should have improved. I too am a member of the about-a-gallon-per-pass club.
