Thanks guys - yes, I was wondering about intercooler function - but as the turbo did boost and the problem was more off-boost lethargy, unless the thing is partially blocked (or blockage else where in the inlet tract), I don't think that this can be it.
I do think that the MAF is the likely (and usual) culprit. I'll make a note of the MAF figures - I don't know what they should be. Live data provides both measured MAF and "requested" MAF. I'll see whether I can get these numbers and post it here both at idle, and on load.
Shame I didn't have my diagnostic kit on holiday - I suspect that the problem would be much more obvious in live data when the running problem was so evident!
