Other items such as catless race pipes, may require a different tune. We can tune both EU and USA cars. Other custom enhancements such as raising the redline, lifting the speed governor, O2 tuning for race cars are available if requested. We test and dyno tune on our own cars to make sure what you get is safe, reliable, and gives you the results you want!

This includes insurance and once we receive the ECU and program it, we will ship it back to you via the method you select at checkout. This ECU cannot be flashed via the OBDII port.

Using a electrical contact pins, we tie into the boards programming mode to read and write the file. We do store your stock file if you ever want to revert.
