oops total typo!!!!!! I meant 35 MPG *not* 65!!!!!! lol

I am surprised though. Really you guys aren't breaking 30 mpg at 65?!? I thought it must be because of low drag and supposed 32 was a normal pre-tune start point.

I noticed my efficiency really drops off fast starting just shy of 70 MPH. (I'd have to recheck, but I think it was 27 MPG or so at 70, and 32MPG at 65). I assumed this was a fuel mix map or something which was getting "richer" at about 2500 rpm, and hoped to "stretch that lean map closer to 3000RPM.

obviously I don't have an uprev tuner cable and do not really know what I'm talking about here. This is why I started the thread. I'm sure there are a few of you out there that have played with the tune this way. My search for this type of info hasn't really come up with much.
