Re: Great results from PCM for Less tuning . . .
Before with the 33" I was getting between 12 - 14 mpg, even on my first H3 with 32" I never got above 14 mpg. Only once when I drove it home new, the first H3 base model did I get 17 mpg and that was driving 55 during the break in period.
I am using 88 octane, which in Montana is the middle grade.
Last night was only on the interstate, so no city driving between the
fillups.
I'm just happy that my mileage didn't go down, I have heard some people have taken a hit with the 35" tires in mpg's.
