Thanks guys, seems silly not to give them a go as they are my nearest as should be geared up for what's needed. It's not the fact I have to wait a few weeks that irritates, it's the no response bit. As you say it's their busiest time I guess.
New Elms must know the car as they did the suspension mods so that's an alternative and possibly won't be seduced by spaniels!
It runs great, goes like a train but it's well over rich as black smoke can be seen on idle and with the screens up it poisons both driver and passenger! Lowering the fuel pressure a tad immediately speeds up the idle but then it gasps at revs, the PO said he'd fiddled with the mapping so I'm guessing its that. Anyway, it'll get sorted.
