Nothing wrong with ONE company supplying the EFI. That's the way it is in nearly every other form of motorsports as well. The EFI simply does what you tell it to do. Provided both work correctly, one will make no more power than another. That said, one "spec" box makes it much easier for tech and will keep guys from having something they are not supposed to. They all have the same injector, same ECU, same Throttle Body, same coils.......other than that, they can do whatever they want to do. Holley was likely chosen because there is already a relationship with NHRA on the COPO stockers, which COME with Holley from the factory. People say, "boy, I bet that cost you guys a lot"...........actually NO, it cost us NOTHING to be chosen by NHRA to supply the ECUs. The boxes, throttle bodies and injectors are serialized and you can only buy these if you are a Pro-Stock team and we know who has what and how many.

Previously, they were all limited to the same ignition box, same coil and they ran carbs..............so what exactly is radically different now and "tying their hands" from a parts selection aspect.
