UPDATE: so my son and I started looking around the vaccuum tubes that lead from the N75 solenoid on the firewall we, put our hands down the back of the engine top left and reved engine we could feel air hitting our hands, so knew there was an air leak somewhere round there, but it was late on and getting dark, so my son took it to a local garage the morning after told the mechanic where we felt the air so they stuck it on a lift to look under neath, he spotted the problem within seconds....apparently the previous owner had taken the main air feed pipe off the turbo, but couldnt get it back on again so it was only half over the hole.
 
the mechanic said theres a triagle clip or something that hiolds the pipe in place and its a bugger to get back on properly, he did it and secured the pipe, my son says its a different car, after he booted it up a hill he said it chucked a ****e load of black smoke out then nothing, pulls like a steam train no more loss of power or rattling sound (which we assume was the half open pipe vibrating when the turbo kicked in)
 
we are still going to do the turbo clean with the mr muscle later on
 
so he replaced the MAF sensor which was faulty - £57 from ECP
and the mechanic charged him £10 for the job of putting the turbo pipe back on.
 
all in all a good result.
