Gas Mileage- Results- 20% improvement !

[Rain]

I drive the black Corvette like a bat out of hell, even at 80ishmph on the interstate, and I see no less than 33mpg.
Last trip down the Natchez Trace from jackson to natchez, ms gave me 38.3 mpg doing the posted speed limit.
(no passing, no stop n go, no red lights the entire stretch of road)

Gotta LOVE a small block Chevy and a 6-speed transmission!
