Metro owner mulling over swap to XFi transmission and 1-ring pistons

[MetroMPG]

PS - I don't mean to come off sounding unhelpful. I agonized about doing the 3.52 final drive swap before I just dove in and did it. So I can identify with your concerns.

But to put it in perspective: Even after going to the tallest final drive, I would install an even taller 5th gear if I could.
