On a RR i use in Ireland that gives consistant figures as JKM rollers with just a remapp (aggressive one) i reached 236bhp. I then added an EVOM's intake, a full Miltek TBE, autotech fuel pump and Forge twintercooler and got the map tweaked so my average power on the same rollers is now 285bhp. The ko3 ain't a bad turbo.
