Yep, I'm thinking 4MPG may be out of reach, at least for me and it seems yourself. Going to try the 91 tune next when I fill up the next time. Curious to see what that does but I'm not expecting much more in regards to MPG.
I've been trying to figure out a few things on it. I messed with the Throttle Boost and took it all the way to 13.5 but I don't see any difference. What exactly does the Throttle Boost do?
