Tried and tested performance! 
After two solid years of testing and development on our own demo car, PERON is proud to launch our performance tuning files for general release. The traditional methods of tuning a turbo factory ECU need to be re-thought when tuning the 2.0T Ecoboost engine. The load needs to be controlled in such a way that the throttle does not close when higher boost or aggressive timing is requested. PERON is proud to keep our throttle wide open with zero closure and also give you factory-like throttle control and drivability. We truly believe we are the market leader when it comes to the 2.0T Ecoboost with hundreds of dyno hours and road miles behind us.

Spec List

  • Make the most from your stock turbo Ford Focus ST250

  • Eliminates throttle closure issues and agitated throttle control associated with competitors tuning 

  • Makes between 265-280whp on the factory turbo. We offer mild tuning for 95RON fuel and more aggressive tuning for cars with forge pistons and meth injection installed. Our production 97RON tuning gives a consistent 280-290hp crank power, with lots left for customers wanting more. 

Putting you in control
PERON introduce the PERON Programmer to give you the power to flash your car with our ultimate performance tuning files and return your car to stock at any time you want. The PERON Programmer is an USB to OBD interface that quickly and easily reads your stock file and allows you to save / email that tune to us so we can build you a performance file.
