Just thought I would share with you that I am no longer seeing this on my car. I had a engine fault light come on last week, the diagnosis was a hole in the intercooler pipe. Thats been replaced with a throttle body clean and also a new overrun valve. one of the 3 must have cleared the hesitation, the car is now lovely and smooth across the whole boost range.

Yeah thanks for that, as i'm just beginning to get a lack of power at certain times, usually just after startup off the drive. Will keep this in mind and get it checked out.
