need to know if anyone has used the AEM system p/n 30-1401 for a 94-95 5.0 and used it for a 87-93 5.0 ecu computer. i called tech support for AEM and the gentlemen said i would probaly have to re-pin the connections, but he also said he was unsure if the sofeware would work. let me know if any body has tried this, or should i just buy the correct system. thanks
