Just booked my car in for a full service with my local garage, if it doesn't improve I'm guessing I could have the same problem

Just had the pressure converter for the large turbo replaced by an independent specialist for 240 total.

The symptoms were a loss of boost (power) above 1500rpm, giving glacial acceleration, with was somewhat intermittent in first & second gears.

The result is now stronger acceleration than I had when I thought the car was running perfectly!
