How the hell can we be sure that the 2nd turbo kicks and is working
100% ok?

I have boost from 1800 rpms from my 1st turbo,and I can hear it very
loud and clear.Also the car pushes very nice with low end torque which
is provided fr the 1st turbo.
But when I pass the 4000-4200 rpms I don't feel the 2nd turbo so good.
I think I should feel that 2nd push...
I do get 10-11 psi of boost though on my boost gauge which is the normal
stock pressure.
I don't know,maybe it is me that I am wrong,cause I use to have 400 hp
on the 7M with T04 turbo which pushed hard at the 4000+ rpm range :sarcasm:

I checked the IAC valve and I get about 15 Ω resistance and the book
says 35-44 resistance....is my IAC valve not working? And it mess is up
my 2nd turbo?
