Stage1 MPG experience...check in
#8
I did not see any gains, but mine stayed consistent, which is a good thing since my kit was added in early December before the really cold weather started. I am hoping to see a slight gain once the weather warms up a bit, but can't make that claim just yet.

I've had the upgrade since Jan 1 and I still haven't compaired my mileage Apples-to-Apples. I can't drive the car the same. I've tried but It's just too much fun with the power. I was about 26-28mpg pre-upgrade. After upgrade 23-24mpg and a blast! With warmer weather coming is should go up.
