The two different modules in question regarding performance differences were referred to "in the old days" as # 369 and # 048, with the 369 being "better" ... how those #'s cross to modern day part #'s I have no idea. I used to keep a few known-good OEM modules in my toolbox and had several 369's on hand.
There's also the "Dyna-Mod" which is supposed to beat the 369. That is, if you believe what ya read - here's some info from Thirdgen; you'll want to overlook all the latency table business unless you are in to custom tuning work.
Why the Dyna-mod says it fits 87-93 V8 I don't know; I would expect it to fit 94-95 as well but if you're those year models I'd just call and ask them.
