R33 Boost Controller

[OldSilver]

I plan to fit a TT boost controller in my '96 R33 series 2. But before I fit it, having read the boost controller install guide posted here, (excellent it is too!) I thought I'd try removing the factory restrictor from the red banded hose. When I went to do this I notice my car is configured differently. The solenoid is blanked off (length of hose joining the two pipes), the red banded hose connects one side of the tee to the wastegate, plain hose joins the other side of the tee to the intercooler pipe from the turbo and the third hose connects the tee to a smaller diameter pipe under the intercooler pipes?. The car runs fine but seems underpowered. Apologies if this sound dumb, but I've only had the car a couple of weeks. Why would you bypass the solenoid? Fitting the TT looks easy but I'd like to know why my car is plumbed the way it is before I change it?

All help appreciated,

cheers

Mal.
