We have nothing that will allow the '7427 PCM to run with boost.

In the case of your truck what is done is to run both an EBL Flash ECM and the '7427 PCM. The '7427 PCM stays to run the transmission. With the EBL Flash ECM running the engine.

To do this another set of ECM harness connectors get added to the stock harness. Then the engine control wires are moved from the stock PCM harness connectors to the new connectors.

We have the re-pin information along with the additional connectors to do this.
