im fairly sure he got the AMD remap at AMD. (thurrock essex, right my lakeside shopping)
I will also say that where a maper says they will tailor the map to you they wont be doing a one off map or anything, they will simply make 1 or two small changes to the generic map. Much like any changes you make using an sps controller with revo.
CC
p torque
revo
APR
AMD
you wont go wrong with these..
although another to consider is Forge. not really a mapper thats caught on for SCN, but forge has a fantastic reputation and customer service is spot on.
Im sure i have seen them say to people if you get there map and are not happy they will remove and refund no questions.
But honestly, whatever figures they put up and however these differ, i dont think there is alot in it between each.
