I have a 02 9-5 Aero auto, with stage 3 BSR that I acquired last year. I have been getting 0455 error code thinking that is was related to an earlier fuel pump install I did. Looking at the Boost Control Valve the top hose marked "R" goes to the turbo inlet pipe. The hose marked "R" also has a outlet midway that appears to have a vacuum hose that has broken off. There is a small section attached at the "R" hose. There is a hose that could reach it in the engine compartment that runs towards the passenger side fender just below the line tagged with EVP label. This has been disconnected at least 6 months prior to the error code. It looks like the end of the loose line was closed off as not to use it?

Could this be a part of the tuning setup. I was worried since nothing is connected to outlet on midway on the "R" hose. The performance of the car seems ok but I don't know if it could be better if there was a connected vaccum line and is this the cause of the 0455 error since it is connected to evap system. I had read somewhere in the threads about a common vacuum line plugged with a bolt and was unsure if this is it.

Thanks
