I had 3 dyno runs before and 3 runs after install. We used the best of 3 on each so the comparison would not be skewed.
I've been watching my gas mileage go from 22 to 21 to 20 to 19 and now 18.9. I suspect my oil has lost some of its viscosity, but I'm going to change it tonight and see what happens. So unlike me to go this long without an oil change, but I've been too busy posting on this forum.
