Ok I have tried check valves and stuff what else can i do to lose the map code? It has to be because of the boost. Does anyone know how to bypass this? 2000 max turbo.Sorry the computer keeps thorwing a map code.

 

I don't know the specifics of what you are talking about, but if it's something that you think is expecting to see vacuum all the time but it isn't because you are boosted, you could just hook up a vacuum canister and check valve just like they do with MEVI/00VI.
