All "included items" come as part of the base kit. Upgrades are as desired.


  • Onboard Wideband - This has a controller in the ecu and prewired harness and sensor. HIGHLY RECOMENDED
  • AFM Delete Tube - This will replace the stock AFM and retain air box. Not needed if turboed
  • Knock Sensor Kit - Adds one knock sensor to plug into stock harness
  • Flex Fuel Kit - Flex fuel sensor and plug and play wiring.
  • Boost Controller Kit - MAC solenoid prewired with vacuum fittings and hose.
  • Upgraded Fuel Injector Harness - This changes the pairing of injectors from 2 banks of 3 to 3 banks of 2. This is only needed with very large injectors to help with achieving a smoother idle with stable pulse widths.
  • LS Coil Kit - Wasted spark coil setup that plugs into the ECU
  • Single Coil Kit - Wasted spark coil setup that plugs directly into the ECU using just a single coil (no mount included)
