I was getting upper 20's with stock PI swap and 3.73 through an auto when i would drive from NJ to FL. It dropped a lot with the P&P heads and cams and i don't do much highway anymore either so if i hit 18mpg i'm happy.

trap I'm going 30 mph just like it reads.Justin is the person who handles
all the Speedcals and can give you the codes.I think the only Speedcal
to consider is the Dallas Mustang Speedcal.
