2020 Ford Mustang Shelby GT500 Gets Power Bump With Simple Tune
No one in their right mind would call the all-new 2020 Ford Mustang Shelby GT500 a slow car. With a manufacturer-claimed 760 horsepower at the flywheel, the supercharged super-'Stang is about the furthest thing from it, far exceeding the Dodge Challenger SRT Hellcat in terms of peak output and nearly matching the sensational Hellcat Redeye.
That said, there's always room to grow, and Mustang tuner Ken Bjonnes of Palm Beach Dyno set out last month to show what a few software tweaks can accomplish. Working with customer Lee Dennis's 2020 Shelby GT500 on the dynamometer, Ken reprogrammed the engine control unit to make full use of 93-octane gasoline and bumped the redline by 500 rpm.
The results are pretty dramatic.
