World class automotive performance software provided by JR Auto Performance.
As the sole USA dealer for JR Auto Performance we guarantee to provide the highest quality service and turn around speed. Generally we can tune and return ship ECUs the same day that we receive them, in partnership with FedEx Overnight services we're able to minimize your down time to just 2 days.
A car with a turbocharged engine (turbine or compressor) can be strengthened with an electronic modification of the software in the ECU by about 20-30%. Our tuning modification changes includes: the boost target levels and limiters, the pressure characteristics of the turbine,the ignition angle, the injection time and angle, lambda map calibration, speed limit governor removed and more.
Each modification is analyzed and prepared individually for a particular car. Before the modification begins, we perform basic diagnostic in order to examine and assess the technical condition of the engine and components.
