Chip?

Anybody ever put a chip in their m3 in order to boost gas mileage? If so, what is your gas mileage now vs. the 20mpg on the hwy they are supposed to get.

My guess is that once the new 14's come out next summer, the e90 mkt value will plummet especially after a couple of years when the leases of 14's come back.
