Attention: TDR Forum Junkies 
Greetings one and all,
Just saw a ad in diesel power mag. for a plug in tuner called mileage miser,
Has the Granatelli name on it called the big G. The claim a 3 mpg increase or your money back in first 30 days of use.
Has anyone tried this device yet and if so what were your results.
Thanks in advance
