Bumping this since I decided to give the 034 tune a try. I wrote some more
here but these are some highlights.
1. Out of the box it was not that impressive.
2. 034 showed great customer support and took some suggestions I had and revised a tune for me.
3. The revised (D) mode is very good - best tune I have tried (also have tried Cobb, Strat, EQT, ED, APR)
4. If you decide to use their DSG tune ask them to make available the "increased drive shiftpoints" version so you can try it, I think it is much better than the standard tune.
DSG tunes involve a great deal of personal preference so as good as I think it is it won't be for everyone.
