High boost error code

[5akman]

Patient: the truck in my signature. I had high boost readings on my Quad (up to 50 psi at idle) and those numbers dropped about 10 psi with the install of a new DAP map sensor. I then removed the Quad unit and sent just module to DAP to be checked out. While I had the Quad being checked, I installed my old Edge EZ. The module didn't have any issues so they sent it back to me and I have not reinstalled it. With the EZ, I get an almost constant "high boost " error code even after replacing the map sensor a second time. I was able to keep the light off long enough to get a smog check done but I now want to sell the truck and I need to figure out this error code issue. Can anyone offer any suggestions on where to start trouble shooting this? Is the MAP sensor terminal end wiring replaceable, I have not checked to see if it is. 

Thanks!

Boost fooler damaged on the Quadzilla module?

 

Wiring issues to the Quadzilla module? Proper wiring used on the Quadzilla? (No hacking up the connector to fit a later series?)

 

Since the boost number is high on the Quadzilla I would have both the module and the wiring checked.
