With regard to the software flashes at the Dealer: You have already stated that your car is out of warranty, when servicing your GTI you can request that no flashes are applied. You are already running a different map, what use would the std flash be to you? I am sure if you keep in touch with your Revo agent you will be informed of any updates that are needed. Forge DV: if it fails, then I will get it fixed. Sure it will be fine for at least a couple of months/year.
Have you taken the plunge yet? If so which option did you go with and are you happy with the results?Also where on the site do you go to add pictures and other details?
