Benzerello

I'm new to this forum ,, on my 1st impreza 02 wrx ,, I took it for a dyno run as soon as I got it to see its present state - it has a td 05 turbo on it and an ecutek map .. The map said it was supposed to be running 1 bar of pressure ,, but it would only reach 0.6 bar,,, the av was leaking a bit - changed it ,, unsure about the solenoid as when the pipes were reversed it went up to 1 bar - so I put a new solenoid on ., now it seems to boost some , but levels out too quickly - checked intercooler pipe work - all ok , pil is present and correct -- any advice anybody please
