550cc injector problem

installed my 550cc injectors and the car ran like ran like shit, amost like the spark plug wires where mixed up but they were right. i dont have my pump in yet cuz im waiting on my regualtor, would that be the problem? the stock pump cant keep enough pressure because the holes in the injectors are so big? i took them out and put the old ones back in and it ran fine. i also played around with the safc too, i stated on low-thr and started at the base line of -18% and i coudnt even get it to idle right.

Set the Lo-throttle points to -10% across the RPM range. Make sure you have 4 cyl selected under "car select" and the arrow points up for thottle. Then make sure you select "Karmen" freqency for the air flow in the settings. Once you do all that and if it still does nothing then recheck your wiring and make sure its hooked up right!

Just out of curiousity, why would you suggest -10%? I was under the assumption that it should be -18%.

(450/550) - 1 = -18%
