Hi ppl!

I began to restore my car since last year (scoupe GT), and I'm almost finished! I have a upgrade a engine with other turbo and a intercooler, and i want install a dump valve/bov but therein lies the problem! I have a turbo boost gauge and the car make a good pressure and is very stable! But if i connect a bov the rpm almost going down, and the engine he even go down! or almost ... if i dont have a bov connect, no problem, but with her the car gets very unstable rotation and can not stand and ends up going down ... I have no leaks .. .. (unlikely I checked all)

It's weird because I've ever had a VW G40 and I've never had a problem of this type, and as others of the same model, turbo, have one and it works perfectly, so in my also have to work! :(

Anyone have ideas to help me?
