Ditto, my mileage dropped just a tad but then again I have a real time keeping my foot out of the gas

Disregard what the manufacturer's claims are. However, some forum members say they see an increase and others a decrease. Personally, it depends on how disciplined you are, keeping your foot out of it. The real clincher is that you get a definate performance gain with minor to no impact on fuel economy. IMO, you can't beat that.

I just turned the credit card over to Brenspeed and gave them the car info. I will report back on my experience with milage and performance. I'm usually fairly disciplined on the open road but there are times when you have to merge with traffic on those long open on ramps to the turnpike.
