We will be collecting our new Plus Four this month -I'm popping over to see it on Tuesday as it should be just finished or very close- and am looking forward to it enormously. In our case we have opted for the Aero Racing manifold, which we have been assured , makes a big difference. So, by the time we have driven to Shropshire and back to Kent and then home to SouthWest France we should have a good idea of how it is responding and will let you know.
