If putting pcm in my 94 JGC ZJ from another 94 jeep. My jeep is 8cyl other jeep was 6cyl, Same part number. Will this matter?

What is your question?

I changed pcm in my 94 Jeep GC ZJ. Got other pcm from 94 jeep grand Cherokee that was 6cyl. Does that matter? Part# was the same. Jeep started(s) right up and all problems gone. Now it doesn't seem like it's getting enough power. Like a vacuum leak. Please advise.
