If I can get mine to do 25-30mpg city and 35 highway with a 5 speed transmission and Megasquirt EFI I will be very happy.

EPA says 18/24 for the automatic, 18/26 for the 5 speed. I believe them.
Man tjts,

Seems sort of complicated. Can this be done on the 190D only? Did it change the fuel consumption by much? How about performance?

Thanks,
Dave
