You could try John Warrington Motorcycles on 01653 698258, he has a great reputation and I know a few people who used him for other makes, worth a call to ask.
Not int he North, but if you get stuck you could try CJS Racing, again I am not sure about KTM, but he is recognized as a top Ducati guru and does loads of bikes, did a fantastic job on my Yamaha S10, also seems very honest and will say exactly what he can and cannot do. He showed me his software, how he reads, decodes and alters maps and spent about 5 hours getting the bike absolutely perfect on the Dyno.
Try Hammer and Tongs in Warrington, spoke to them just before Christmas and they know a lot about the 1190's. Said they can de-cat original headers for £110 and remap was £400 if I remember correctly. That's where I'll be going in the near future anyway.
I have used hill top before for a GS, it made a difference, did not cost a lot, I watched them do it,,,,,,,,,,,, they offer money back if you not happy (or Did) I asked about Ducati 1200 S they told me not to waste my money as it would not make a lot of difference. But certainly some interesting reading in that thread
