Default problems with VAFC (noob on the Apexi system)

i managed to get a VAFC for my honda civic but for some reason im gettin the CEL code is : Hi Baro/MAP voltage read. the car is turbo and i have no idea if i am getting this problem because i have the Map sensor with check valves (wich should not let the map read boost) or for another reason. Any response or ideas is greatly apretiated

Use a a big brake booster check valve and one of those universal vaccum tees from NAPA. Problem solved.

He's probably running the stoc MAP sensor with with big injectors trimmed WAY down. Otherwise why would he have check valves at all?
