Default throwing code when boosting?

I have a Z6 w/ greddy turbo kit and custom intercooler setup and currently running an FMU at 5lbs. I tried running check valves to reroute the boost past the MAP sensor but it seems that Im not doing it right. When I boost for a few minutes its ok, but when I lay on it it throws a check engine light then runs rich as hell and idles around 1100 rpm. Ive got no clue. help me please.

MAP sensor will always fail, no matter if your engine is cold or warm...

As soon as MAP sensor see's boost, it'll go in CEL....

Just keep adding check valves. My old A6 took 4 before it would stop throwing a MAP CEL.
