Not just a tune:
Larger lower pulley
AF1 intake
Mickey Thompson ET Streets


and the "tune"


everything else, stock 3:55 rear end, independent suspension, factory.

 

Learning how the vehicle is designed, and retraining your driving habits will net a large gain in the MPG world, more than tunes will IMO

 

However, no matter what else was changed, the originator questioned tunes that were mail order, and mine certainly was. Once the car was put on the dyno after achieving the 11.65 @ 122mph, very little was changed in the mail order tune. The car eventually went 11.22 @ 122mph.

 

The Livernois tuner is hands down the best for the Ecobeast. I can twist 46's with the 93 tune and stock gears.
