Less expensive than the PC and on the plus side allows the ECU to use the sensors properly, MAP, IAT, oil temp., injector wear, etc.
Nothing the others can do that the PC-5/AT don't do better. You get what you pay for..... That said I would like to see a write up on the others, with dyno runs..... On paper they dont have no where near the features of the PC-5/AT combo.... well... except for the fact that they leave you with more beer money.... which is a good thing.....
