550 injectors? to 50lb , are they hi impedance or not?

[mikesloud]

OK I have super afc2 , a remapped tuned ecu , but it is tuned for 550 cc injectors, I already have the msd 50lb injectors, how close are these to 550cc and will they work if I fine tune fuel curve with super afc . Or will they not work and have to spend more money on 550cc injectors, I hope they are close so I will not have to spend more money. Can anyone tell specs 50lbmsd verses 550cc . any help appreciated!!!

You can get the MSD top feeds in high and low impedence IIRC but most common are high...

550cc = 52.38lbs/hr, so the ECU is tuned for larger injectors...you'll have to add a little fuel.

FYI, 50lb injectors = 525cc (multiply lbs/hr times 10.5 to get cc/min)
