Can you specifically explain how the dinantronics piggyback unit ties directly into the factory ECU to a degree that the Burger Motorsports JB4 does not? It is hard to understand how that is the case when you are utilizing the same connectors they are.
It is my understanding that the encryption for the N20 and N55 engines has yet to be cracked, which means that Dinan cannot access the actual ECU parameters/maps anymore than any other tuner could.
This quote from your website is patently false, to to the best of my knowledge:

The DINANTRONICS™ Performance Tuner uniquely has the capability to adjust target Lambda, correct short term trim as well as ignition timing errors induced by raising boost pressure. This enables Dinan calibration engineers to optimize air/fuel mixture and ignition timing at elevated boost pressure throughout the entire gamut of engine RPM and engine load.

With the N55 and N20 engines how can you adjust target Lambda when no flash tuning exists outside of a select few 2011 models with the proper DME? Further, are you saying that you can correct timing errors simply by raising boost? If that is the case, any piggyback would be able to do so (surely you are not claiming that only Dinan piggybacks can raise boost).
Are you really claiming to be able to manipulate AFR ratios at specific RPMs when no other tuner can? Do you have hard data to back this up?
