Additional information

There is even a scramble input to apply an additional amount of CO2 when you need it any time during your run. The built in test mode will allow you to test the CO2 boost controller at any time with the engine not running. Just add CO2 and test away. 

Provides one wiring harness, wastegate CO2 pressure sensor and CO2 manifold. Tubing, tubing connectors, and mounting hardware sold separately. Will need the Boost option enabled in order for this to function. 

Parts Included: One wiring harness, One wastegate CO2 pressure sensor, (1) CO2 solenoid block.
