Anyone To Map My VEMS On Audi ABZ V8?

[Siena]

Hi guys,

I've got the car running and driving, though lots of shunting under load, I can't even get her MOT'd due to the rough running. 

I'm at the end of my tether - is there anyone that could help me map / tune her? I'm in the Suffolk area, but will travel within reason, and pay anyone that could help me a fair price. My car's been off the road since first week August, and public transport is draining my resources.

Thanks in advance.
