Bingo! You win the prize for the post I most agree with!

The spacing on the MTX-75 keeps the duratech in its powerband through every gear. I wouldn't change the ratios at all except to add a 6th gear for fuel economy at highway cruise. Although I have to admit that 26.5 MPH in a 300HP turbo car cruising at 80MPH in 5th; at 3700 rpm for christs sake is nothing to laugh at. The more I drive it around the more I am glad I left the final drive alone. Yes I have traction issues, but I can always get wider tires.
