Yeah, sorry.

^_^ yes my Speedo is actually substantially off in two ways. . .

The person before me had massive rims(18s) which biased the system slightly low. Once I removed that set and replaced with 13s gas mileage went up drastically because the uniform motion sucks up massive amounts of energy on bigger tires.

The difference in RPM is kinda small. at 1:1 engine wheel spin you lose 6-7(104-97) mph at 2500 rpm, while the MPG change was from 25-33.
