so far I have tried it only on the performance mode and have not taken it to a track to see actual #'s ,however i have taken a short run inroads I normally travel abiding the speed limits and trying to get mileage and have exceeded normal mpg.up and down hills garage to garage and over 35 miles 31.7mpg.I'll try it on a road trip and reset it to best mileage program. I'll let you know what happens. I do hypermile when safe. It is great to have all the power and still be able to economies.

Does what the write up says....

Reviewed By Noel L (POLK CITY, FL) Reviewed for a 2007 Chevy Corvette —12/3/2015 6:20 AM

Certainly has increased take off acceleration, At 85 and above the car feels different somehow very light and fully responsive literally feels like nothing is too much for it, a little disappointed the programming did not include individual gear change ratios but I still need to get back in there and adjust what I can as I have only adjusted the power as of now, my Vette does have a K&N filter system and axle back SLP loudmouths that have helped with speed improvement gained from the Max program
