I thought the 93 ECM did not remember what it had "learned" like the 94+ PCMs meaning if you put 24lbs injectors in it without a retune you are going to be a fair bit too rich till the engine and unheated O2s finally warm up and take control. Best case there is you will wear the engine like it had a carburetor on it. I might fool around with a 2lbs difference on the later pcms for a short term fix since they do learn and have heated O2s that react faster but on a 93 no I would not.

OP You can move up to 24# injectors, but you'd need a good tune. As stated above, with SD and non-heated O2s you'd run rich.
