MRC sound pretty good, have heard a lot of good things about them so I may look at one of their custom maps, Im a bit sceptical though because I emailed them my mods asking them what sort of figures i might produce and asking about a k04s which is like a hybrid k04 and I got this
'Your car as it stands should be looking at getting 290bhp, although every car is differnet and we cannot promise numbers. We won't push a car beyond what we think is safe. '
I definately put k03s down in my mods list as my turbo, even if it was possible there would be no way id want more than 250 out of my k03s as it would just go pop, i was looking at my options more than anything and am not slating them just thought it was funny about 290bhp from a k03s
