TuneECU for Kawasaki???

I've been using tuneECU now on my bike and I love it.
I was wondering if anyone knew of anybody else that did similar for Kawasaki?
My mate has an 06 zx10r and I've been trying to find something but all I can find is kit ECU's and a guy called Guhl who claims to get an extra 18hp by just reflashing the ECU. (11 model)
I can't believe that it is this hard.
I tell you what, SD's may be a little more pricey but the brotherhood more than makes up for it.
Everything is for a dollar on the Jap performance side!
TRE modules and GiPro's....
Any help would be great...

Thanks for that mate.
I've managed to track down someone but am having trouble getting on to him as it's a bit of a cold call.
Was wondering if anyone on the forum knows or has dealings with Stefan Briege?
I think he is based in Europe (Germany?) I was given his Facebook page but I sent a message and I'm not going to stalk him, but if anyone knows of a way to contact him (long shot, big world, small bike community) Or heard of his work?
