I don't see the need for yet ANOTHER box on the car, unless maybe I'm misunderstanding the box that Active installed on the car. Regardless he is obviously pushing the limits, I mean Q16 is kinda cheating in a way, its like nitromethane toned way the F down.
You raise some good points.

They need to keep the stock ECU as the AEM doesn't seem to be capable of handling VANOS and by removing the factory DME it will create issues. So, they need to run it as a piggy essentially.
