I was wondering what mileage increase anyone has seen with the .658 5th gear. I have a 2000 jetta tdi.

I saw none but rpm were lower. It was a fun project but if I had to do it again, I would have gone with slightly larger tires. It really depends on how often you drive highway. Some have claimed a small increase.
