I think their map for K04 must be a lot better than K03 & IHI turbo. I kid you not, it dyno'd 226bhp. It didnt drive bad at all, it was quite linear but just didnt pull hard.
Im not trying to talk you in to any certain map, its just my experience. My car had no faults, leaks or boost problems. 2 weeks later with REVO on it ran 276Bhp.
