High-pressure MAP adapter cable is designed to add a high-pressure transducer in conjunction with your factory MAP sensor. This harness gives the factory ECM the ability to read up to 185psi of boost.
When ordering your sensor you want to pick the closest possible sensor to the amount of boost you are running. If you order a 185psi sensor and are only running 70psi of boost you will loose a substantial amount of accuracy and it will only make your tuners life harder.
