LCR n75 pipe removal - which one?

[dicko's]

NO doubt the title will be edited to suit, but ive got a problem with the LCR boosting, its running an n75 and a manual boost controller, ive removed the boost controller, car still has boost problems, boosting all over the place and dropping off, wont hold boost properly at all

I want to try it without the n75 valve in, just the boost controller, but as the n75 has 3 pipes going to it and the bleed valve only has 2, which pipe is surplus to requirements and can be blocked off?

thanks

Just a guess but it might be the one that goes to the charge pipe. I think this one only tell the N75 how much boost is coming from the turbo.
But like I said that is just a guess.
