I was just wondering if anyone has any input on how good the Granatelli Mileage Miser is and how good of mileage increase they got out of it since they claim they guarantee at least 3 mpg differance I was trying to figure out if I'd rather invest in it or the EZ thanks for any of the help

 

I believe it is just a rebadged quadzilla xzt. EZ adds power and mileage the same way. Either one should work for ya, just don't expect to get the advertised gains in mileage.
