Mr. P Body, What do you use to measure back pressure? I would love to learn this.
I had a great tool at the Dodge dealer when I worked there. We had a lab Scope adapter setup for the DRBIII and part of it was an adapter/transducer that screwed in where the 02 sensor went. Then as long as the DRBIII had the Pep module on it it had a spot where you could read pressure and it worked great. It also had a transducer to read fuel pressure and an Inclinometer. But basically the transducer to read pressure screwed right into the 02 sensor bung. Ron
