MTM, ABT, Oettinger, Superchips, AMD (which I suspect is a rebadged Superchips remap) all do remaps for the 2.0tdi. Revo mentioned that they have one in development as have Jabba. Best overall power output seems to be the MTM remap (also the most expensive). ABT is the poorest output of all the remaps I've seen, very conservative and not too cheap either. The Superchips remap seems to be good value. No doubt AMD's magic rollers will make their offering appear to be the highest output.
Remember that despite all the [censored] that some of these companies will spin none of them offer custom remaps. Also the power/torque at the flywheel figures that they all quote are rough guesstimates (some rougher than others).
