Gas Mileage

[MeetMeAtThePark]

I had an 03 cobra in the past that had an upper pulley with a tune and the gas mileage improved once that was on. Have ya'll seen or heard any reports of gas mileage changing up or down after a pulley/tune install? Thanks.

Certainly. Although you are spinning the blower faster, your tune will be slightly leaner (but very safe) than stock. You'll only see less mpg when you put your foot in it.

I'm running 700+ at the tires and get 21mpg at 60-65 mph with 4.10 with our tunes.

The problem is, you won't keep your foot out of it! :banana:
