have you checked your ECU for fault codes? If not there's loads of threads on here that'll advise on how to do it. Should let you know if it's a sensor related issue.

 

Do a search on it. There's loads of threads on this topic, but basically, it's a trait of many a Scoob. After the 2nd-3rd time you floor it, the boost returns as normal!
