That's really what's getting me. Yours and the Dryden tail work very well but are quite a bit more aggressive than the template. Just not TOO aggressive apparently.
(And your RV is doubling my latest 9000 mile average. Diesel/gas is in there, but still, DOUBLE for about the same frontal area.)

What kind of vehicle are we talking about? Maybe you've got other issues, like plugged air cleaner, over rich injectors, etc. Or, you're not coming out of open loop. Is it gas or diesel?
