Does anyone have proof that diablosport handheld tuner will increase gas mileage on 2005+ mustang V6 with manual transmission? I know that diablo states that it will ,but also know that marketing pitches come into play when trying sell products.

Ya Mine Does, As Long As U Keep Your Foot Out Of It. The Big Plus Is That Now I Can Scan My Car For Any Troble Codes. I Think It Would Take A While To Pay For The Tuner If Your Just Buying It For Gas Savings. But Over A Year It Would Be Like It.

I got a diablosport with a performance tune, you would need to get a gas saver tune, I think. Cause with my performance tune I certainly don't knotice an increase in mine. Just a HP gain.

Problem is any gains are usually offset by the extra fun of hitting the accelerator!

haha! So true. It's just so hard not to. It's maddening!

yeah I done the diablosport tuner with the steeda cai and I love how the car pulls now. when you hit the gas a little it pulls you back in the seat a little and I love it. I would likt to get a set of headers for it next, but I think I will wait until my warranty expires first then put the headers on it.
