1. Check for air leaks and split pipes
2. MAF's can play up so look at that.
3. DV's are also know to fail so this is another place to look.

Do you have VAG-com? It would be useful to log your MAF readings, as i suspect its borderline faulty, so its not showing a code as yet, but giving you poor perfomance
