ok so i have new injectors for my car, 890 pri and 1000 sec, i'm just wondering how crappy will my car run if at all with a rtek 1.7 ecu . I'm switching everything over to a megasquirt system but i wanted to drive my car to a few car shows around here untill i'm done building the megasquirt.
or should i just pull everything out and put it back to 550/890's?

thanks
