I'm doing pretty well in the old ZX2. I've had a few tanks over 50mpg but only in highway driving. For me, it's easy to get over 50mpg on pure highway trips. My commute involves too much city driving, or else I would be getting 50mpg tanks commuting. Otherwise I have been pushing every closer to 50mpg on my commute with some recent mods. I believe if I can get the latest mods to work consistantly, then I can achieve 50mpg consistantly.
BTW, no EOC for me, just a nice low idle gph of 0.20, but it can range down to 0.08
This helps a lottt!
