Dont know of anyone out that way sorry
I wouldnt go anywhere that maps on the Dyno personaly either go with Ginga suggestions both of which are well known to have done a lot of good work mapping or take your car to Hiteq or Rod Bell anfd let them do it.
The Mapping will be the make or break of your cars performance and drivability dont skimp on it use well known mappers who are careful with your car.
I had mine mapped at Hiteq by Ian and its superb loads of pull from low down in the revs fantastic throttle response and good power on boost idles fine even from cold.
If the mapper doesnt have at least one other form of knock indication then run a mile.
Thanks
Paul
