As you can argue that the car can only be tested to the same as MOT standard (on tickover) 8 injectors gives you the best chance of passing with a tuned engine.
Maybe I wasted my cash, but at least I feel safe if pulled over.
Your emissions have as much chance of being illegal with an 8 injector set up as they do on a 4 injector set up. It's all down to the mapper and condition of the car...
