The valve spring explains your map signal. Have pic of the engine bay before you took it apart? Still like to see that log.

still trying to wrap my head around what you are getting at with the map signal. It went all the way back to october of last year through my logs when my engine was completely stock. The MAP looks EXACTLY like it does now. And it ran great then. Same tiny little dips WOT, same max KPA, etc. And the only thing common between the current motor was the shortblock. Let me post some pics....
