This is an electronic device designed to properly raise the factory fuel cut level on factory turbocharged vehicles. If you upgrade your intake, exhaust, or anything that can raise your boost pressure, your ECU will activate a fuel delivery cut-off as a failsafe procedure. 


  • The electronic signal from the FCD will raise the fuel cut level to accommodate for the additional boost without triggering fuel cut and/or an engine diagnostic light
  • The FCD installation is designed to be easily integrated with the VPC/F-CON or factory ECU harness

    Warning: Due to the characteristics of this product, higher than recommended or unsafe boost levels may be attained by the installation and use of the FCD. This may result in severe damage to the vehicles engine or other mechanical parts. We suggest a fuel delivery upgrade and consulting a trained technician before the purchase and use of the FCD.
