What can I check to get the ECU to stop seeing boost and throwing a MAP CEL. I have a Synapse missing link and it doesn't seem to be working. Any help is much appreciated. I've search and I can't find **** that helps me.

 

is it used or new? If it is used it may need to be cleaned out, It it is new it may just be defective.

 

It's new. That's what I figured was wrong with it - being defective BUT that wasn't it. I found the problem. It was something else. Thanks.

 

so what did the problem end up being?

 

Trying to run 240cc injectors.

I was +30 on the injectors, and it was over working the injectors in corralation with the MAP causing a MAP CEL. We put DSM 380cc in and it ran perfecto. No CEL and it dropped the injectors deep into the negatives.
