I had my "chip" installed at Brazels shop last year after the Rally. I can't say for sure we are getting any better MPG but I can testify to the fact that we have more power. We are on a trip East from the Seattle area and I have had to climb both the Cascades and the Rocky's. My speed never went below 40 MPH (2nd Gear)@ 3500 RPMs. For the most part I run up the smaller hills in OD. This was not true before the modification. So far I am satisfied with the investment.
