I am looking to start upgrading with a reflashed ECU and trying to decide between the Works P2 or Xflash. Am I right in thinking the major difference is that the P2 retains the factory solenoid and ECU controlled boost whilst Xflash uses a bleed valve and is there any advantage with the P2 which could justify a $200 price difference? Any advise appreciated.

XFlash has consistently shown to make power gains during independant dyno testing. Just dig up dyno day results and make your decisions.
