Have had both Stage 1 and 2 from Shark on my TSI VRS, very happy with both maps, havent tested stage 2 yet on a RR, but last year my Stage 1 made better figures than quoted, and that was on a dyno which was reading low on quite a few (healthy) standard cars. looking forward to Shark getting their Mk6 Golf GTI to stage 2 as Im sure they will unlock some more potential that I can carry over to my car :-)
