I've been reading though a few threads on this forum is there anywhere I can get swirl flap blanks are they 22 or 33 mm I can only find ones for the m47 engine are they the same I know very little on these and have only read that they can cause some serious issues my car's being mapped a week tomorrow and ideally want it done before mapping to play it safe any info links and advise would be really appreciated
PS I've got a 2007 e82 123d
You don't need any blanks. When I removed the swirl flaps on my old 123d I just took the manifold off and removed all the flaps and associated components and then epoxied in the lever which normally connected to the actuator, it was completely air tight.
Its all self explanatory once you get the manifold off the engine, id definitely advise you to replace all the related seals as when I removed mine they were rather worn and needed replacing.

When I removed my swirl flaps I got a n47 swirl flap rod bung from SF performance (on amazon or eBay). It has two o rings and neatly seals the hole the rod went through into the manifold when you remove the flaps, bearings and actuator rod. There are a number of threads on removing the flaps on the 123d n47, search is your friend.
