Its time to get more power out of your Ford Mustang GT350 with the 5.2L V8. The 2015-2017 model has untapped resources and VR Tuned can help bring this performance out. Gain up to 20 rear wheel horsepower and 25FT/LBs of torque with our ECU Flash. While dyno sheets are great to show where power is made with small gains under 30 horsepower, what is more important is how it drives on the street. Along with improved performance numbers comes better throttle response, faster 0-60mph time, and a stronger top end pull on the highway. Designed for both automatic and manual cars, the automatic Mustang GT's have their shifting cleaned up while the rev limiter on both is raised to give you faster quarter mile times. This is the optimal tune for 93 octane vehicles. 91 octane cars can expect similar performance but with slightly reduced figures. We alter the factory timing and fueling maps to offer reliable, safe, and strong peak performance gains.  All tuning is done via the OBD2 port using the new HP Tuners MPVI2 system.

Crank Horsepower Ratings:

  • Stock Power: 526hp | 429ft/lbs
  • Tuned Power: 546hp | 454ft/lbs

What are the benefits of VR Tuned?

  • #1 priority is our customer service to you!
  • Our tuning is used worldwide. We have powered vehicles of all types worldwide including JDM, EU, Australian, and USA cars.
