Much as I hate to ask this question -
What sort of fuel mileage change - and which direction - are we talking about, comparing the Mach 4's to a mild injector like the RV275?
Sign o' tha tymes, unfortunately.

I never ran a 275, but I'm getting 1.5 mpg better on average with the M4s over the DD2s I had. I routinely expect 22 now on the hwy, driving at 72-78mph. This is with no timing box or anything else. Just the m4s.
I last tank was 18.3, in mostly city driving. In fact, in a TDR post a ran the numbers compared to my typical average of 16.2 around town, my hwy mileage was 25+. So either my city or hwy was pretty decent.
