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.
Easy new car.
First we will start off with appearance it has a very good look to it but in my opinion it could be a bit smaller. Installation is very easy, you just answer a couple questions and done. Price I think is a little steep not everyone can just come up with $600 easily but it is what it is. But overall if you want a new powerful ride this is the way to go. Instant power no doubt, just buy it and you will be satisfied.
C7 Corvette - It's Meaner Now
Great product. Very easy to use and you get the fast results that all car owners are after. It only took about 7 minutes and my 2014 C7 Corvette runs better than ever. Pretty amazing on the performance increase and saved me money from what I typically pay for a tune. Highly recommend to all car enthusiast.
