I still think you should take the intercooler off and fill with water to check for leaks, its a very effective way to find boost leaks, I did it on my 330d and I have done it on my Z4 and found leaks on both which gained me allot more ponies and got rid of annoying flat spots.. Its extremely common especially on a high miler like this one.
Its a bloody mission to do a boost leak test on these cars otherwise, I never got it right cause of the surclip designs on all the piping.
