I'm lucky to get 269 bhp on a good day (on JKM's rollers) and I'm Revo Stage 2 with Milltek and Twintake like you.
Robin you could get your settings turned up (still maintaining 100+bhp headroom) and get a sensible 260-270bhp all day long
IIRC you said yours was watered down??
Romany - great result for the mods! Just shows with the right set up, the K03 can be right up there with the stg1 K04's
