My car is slow, and the RPMs aren't what they should be with your kit. What should I do?

Before adjusting clutching RPM, check the following:

  1. Ensure you're running fresh fuel with the required octane rating.
  2. Check for boost leaks using the KWI Boost Leak Tester instructions here.
  3. Verify wastegate crack pressure and boost as per your tuner's instructions using a Mighty-Vac or datalogger like Maptuner or Powervision.
  4. Ensure your intercooler fan is working, and charge temps stay below 150 degrees Fahrenheit.
  5. Use a compression tester to verify good compression in each cylinder.
  6. Check for excessive drivetrain resistance, like binding CVs or dragging brakes.

If you need tools for these checks, consider renting the KWI "performance troubleshooting kit" from our shop.
