I remember quite a fwe people claiming they did but I cant seem to find the posts using the search button. I know for sure Jerry2500 did. I also know a few of the radix guys gained mileage when they put it on with stock sized pulley. Post up your setup and what kind of mileage gain you got if you did.

that's kind of hard to say.
when I got the supercharger I also got a tune to make it work right.
so I am not really sure what gave me an increase of 1.5 mpg.
the supercharger or the tune.
I can say it is a combination of both.

I got something like 3-4 mpg additional when I put the Radix on my Avalanche. The stock tune was for crap and the (updated) Radix tune was killer. From 16 mpg on the way up to Ventura to 19+ mpg on the way back.

i saw a 1-2mpg reduction after all my mods. thats not really saying much though, cause i have a heavy right foot now more than before. I drive 75% highway and 25% around town. i average 13.5mpg.

have not seen anything fall off with the turbo, in town seems to be right on. Now I drive it harder, so I guess that could be an increase in Gas Milage. Have yet to go on a long haul to see what the hwy did.
