Hi all, some people may be aware of this, but I recently bought a Rspec Manual boost controller (which is really just a bleed valve) direct from Rspec on ebay

Still waiting for an explanation from Rspec as why this bleed valve was being marketed as an MBC and why the instructions supplied are wrong.
As I know how to fit a boost controller already I just glanced at the fitting diagram and installed it using the markings on the boost controller (arrow points toward wastegate). Taking the car for a spin i put it on the lowest setting to start and it was spiking wildly and levelling out to 14psi though was having bad fuel cut. So went to have a cup of tea and look at the fitting instructions properly, which is just a crude diagram with no info about the unit. It was then that I noticed that they had included a little sticker which stated arrow points away from wastegate...a complete contradiction to the markings on the unit. Its at this point I realised that to save a bit of money, Rspec had obviously had a faulty batch where the direction of flow arrow had been put on the wrong way so they give you a little sticker to correct their error so they can still sell reject products. This then meant there was no pressure getting to the wastegate actuator to contol the boost (Thank god mitsi put fuel cut on the car as who know what could have happened to my engine/turbos). Now After removing it and installing it as the contradictory sticker stated so that it functions correctly I am still unimpressed. Stock is 8-9 psi. With MBC fitted and with the valve fully closed its at 12-13psi. Piece of junk is now removed and will never be allowed near my car again.
This is a terrible way for a company to behave and should be ashamed of such a poor product that could cause serious damage as it is marketed as, and I quote "suitable for novice or DIY mechanic installation". All I can hope is someone finds this through a search hit to warn them before they blow their engine or their turbo spontaneously combusts.
