does a 19lb. injector deliver less fuel at idle than a 22lb. injector in the same aplication. thank you

Yes, and no. In open loop computer operation the 22 lb injector will be richer than the 19. In closed loop, hot engine, normal operation, the computer will adjust the pulse to get the right mixture. An adjustable fuel pressure regulator is a real good idea with this setup. tom
