the zero plate is full fuel all the time nuttin holdin back.......................so now the governor is in yer right foot.........................you already said " Will the milage come back when I drive it right"

yes is the answer IF you can drive it right .........................watch yer boost gauge and use it as a economy tool.......the lower the boost ya see the better the milage will be ( less motor load)


bottom line here is if ya wanna play ya hafta pay

smoke is unburnt fuel as in a waste the less you blow the better your mpg. also the less boost you build the better mpg.

Less smoke = more mpg

My 97 got 25mpg on the drive home. Three days later a #11 went in and it never got better than 23 again.
