Don't get offended but you own a tuned/turbo car, you should be checking your oil levels regularly. Have you done any track work since the service?

My betty will generally use around half a litre of oil after an rac sprint - 12 hot laps. Some of it is in the catch can and some is burnt away.

Street driving it will use about half a litre per service cycle - 6 months or approx 3000km.

If you are seeing boost regularly and have no catch can you may be ingesting a lot of that oil into the engine. Hopefully you aren't burning it away....
