4l80e swap - combatting MPG loss with gearing
#34
I picked up about 6mpg with my T56 swap with the stock 3.73 gears. This was giving me a cruise RPM of about 1500 at 75mph. I feel like lower cruise RPM will help with MPG a lot, but I do have to downshift to 5th for big hills. Going to 4.56s soon.

How about the city, how much did you gain or lose there?
