I swear that there was a thread on this already but I cannot find it for the life of me.

Anyway, my friend gave me a tuned 1999 GTP PCM and I want to know if it'll work (properly) in my 98 GTP. Some tuning sites list 98 and 99 PCM's together, but I swear I read somewhere that they have different MAF sensors or something along those lines.

Thoughts?
