I just put 2000 miles on my VX after installing a PV2 and dropping
in a K&N filter. I measured the mileage with my GPS and drove with the "Power Drive " on. I was very suprised to have gotten
21-24 mpg on the road and 19-20 around town. This is compared to 16-18 before the changes. Driving at 60 mph average and the AC on yesterday I got 22 mpg on a 300 mile trip. Tires are 265/70/R16 Bridgestone Revos. I also checked the mileage with an on-line map program. The downside is that the PV2 is loud and my wife hates it.
