Rambo555

Wonder if you guys can help, took my wrx 03 for a spin through country roads and gave it a run through the paces but nothing too much, noticed however after a few miles that it boosted much later, almost into 5k rpm and that the bov was a lot quieter and sometimes non existent?

It's a baileys bov and I don't have anything else mod wise as yet to the engine, any suggestions much appreciated

I would say boost leak but I'm no guru.
