If I baby it (NO BOOST) I get 16-17MPG
but having all this power makes you really want to step on it ALL the time...when I REALLY get on it I'm averaging about 13MPG
Keep in mind also that you now need to run 91 or better--I run 93 ...so you have an added expense in Gas costs also..
Others have reported 18-20MPG on their supercharged V6's but I don't see how that I possible...lol...at least not with me
Ross said you can run mid grade, but I haven't bothers trying, rather use 93. Really depends on how advanced the timing is on that tune.
I've been getting 18 mpg average with beating on it most of the time, 22 highway if I keep off it, and that's with heavy 32" tires.
And for you Boston guys, I leave you this
