bought a s2rs and it is running 16 psi through standard cooler, so wanna drop it til i get a new intercooler

i went to do this via the bleed valve and no matter how much i screwed it it made no difference hardly

as the car is now, it runs 16 psi until you flick a switch inside the car, after doing so it flies past 20 and pinks its arse off, the car also has a 5th injector, the electrics are disconnected and the fuel line is bunged up

here is a brief description of my boost system, i tried drawing a picture but it didnt happen

there is what i can only think to be a boost sensor (pic 1) above the fuse box, from which goes a hose that goes to a t piece, one end goes into the car (i suspect boost gauge) the other then goes onto the top of the manifold (left hand side pic 2) the right hand side pipe then dissapears behind the engine, dunno where to, and it has a t piece to the top of the dump valve.

from the turbo a pipe goes into the bleed valve, (left hand side pic 3) the centre hose from the bleed valve runs to the electrical unit in pic 4 (from which is one earth and three other wires to a relay and a few other places, dont really know) . the other (right hand side) then runs to an electrical unit attached to the gearbox

so whats wrong guys? any ideas?

pic 2



pic 3



pic 4





heres all the 5th injector setup



on the electrical unit on pic 4 there are 2 blanked off parts i am left to believe this injector hose and fuel feed run to but im not sure
