I went to see this Golf and there are issues, seems like the previous owner decatted it, fitted induction kit and then it was mapped, the dealer has fitted the sports cat so it would pass an MOT. So if it were me and I was going to Stage 2 a Mk7 would be a full exhaust system, uprated clutch, new coilpacks, uprated spark plugs, injectors cleaned and tested, intercooler and brakes. On this car nowhere near enough has been done in my opinion to run properly or reliably a Stage 2.
