Ive been running the badnewsracing efi live tune for awhile on my car and I must say it absolutely makes the car a more fun car in every aspect. For starters it makes more power than any other tune on the market. The increase in power also comes with better fuel economy as well(if you can keep your foot out of it). The customer service is top notch as well. You dont have to wait days or weeks at a time to get updates are retunes, which by the way when you buy through BNR are free lifetime updates and retunes are unlimited. Its hands down the best tune on the market. It will be on sale on black Friday as well.
Badnewsracing.net is where you can get it and anything else you want to upgrade your car
