Boost problems and questions
My car has great instant boost off the line. It never has the boost drop that I would expect to see when the second turbo and under hard accel the cars seems to fall flat on it's face and generate no power on the top end.
I suspect that the second turbo is not operating properly. I replaced the vacuum lines and now I'm in the process of testing solenoids, etc. Here is my question though....
Can I hurt anything if I force the flap between the two turbos and take the vehicle for a test drive to see if my diagnosis is correct? I'm sure it will feel laggy off the line but at the upper end I will feel more power if I cam correct that my vacuum flapper is sticky or not operating.
I wish I understood more about these but I'm learning!

Yep, you can do that no problem. Car won't care if that flapper is open.
