Neuspeed power module? yes/no?

[zzimbile]

Let me preface this by saying I know very little about tune engineering. However, I'm under the impression that these ECU's run in closed loop most of the time, but what happens when they are in open loop? In open loop wouldn't it be bad to have modified MAF readings with a stock fuel table?

I think, in general, we can agree that piggy backs are not the world's best option. But there are loads of piggy backs that are safe and provide a happy medium for those who do not want to go through a full ECU remap. I know this will not be as good as an APR or flash tune, but it seems as if many people in the VW forum are running this power module with success. I wanted to see if anyone tried it out on our platform.
