Re: Sprint Booster - Gas mileage...
After my initial excitement about this device increasing mileage (saw 30+ mpg on a road trip). I have now checked a couple of tanks around town and just don't see much change from my pre-SB mileage values (getting 18-20 mpg around town - yes, I keep it revved up...). Bottom line: I don't think this does much for mileage! So much for that vain hope!
...Still love the throttle effect though!!!
