Where have you plumbed in the BOV, it sounds like you haven't merged it into the intake properly...
I made a new intake to throttle today, to try and fit the electronic throttle (without the butterfly in it). The cable throttle has been working flawlessly but the cams still arent working, even with the gutted electronic one still plugged in.
The turbosmart BOV needs a much stiffer spring too, I had it venting and it leaked badly, I removed the hose and it still leaked on boost. Blanking the hole caused the hoses to pop off, ruining the under-bonnet sound deadener.
The Fcon has a miss which im not happy about, probably caused by the emanage being in the circuit still. That and the cams not coming on make it feel very laggy, it feels dead down low until I get above 4k, looks like the Emanage is the better option at the moment. I may end up going with the PS2000 soon if this goes nowhere.
