update my prom memcal?
I've been having a problem with my 1993 C1500 5.7L stalling at low idle. After replacing the IAC, EGR, throttle body, distributor & ignition coil, and knock sensor, we did some probing on the wires connected to both the distributor and knock sensor, and ECM. We've narrowed the problem down to the PROM. How do i go about updating it? Or is it easier to just get one from a junkyard?

Are you tuning this setup?
