There are two main types of DSG as I understand it, the earlier Mk5's (upto the 09 run out cars like the Pirelli etc) use the older protocol and have plenty of remaps available for them, the newer boxes (Mk6 Golf GTI, Golf R and facelift S-Tronic S3) are on the newer protocol controllers and can be remapped but people like Revo still haven't released anything for them. The options at present for these are from the likes of HPA but as Keith said earlier in the thread this is going to change towards the end of the year with more becoming available.
