    PCM matching service #, matching hardware #, different codes YCTJ, YCTK

    Guys, I'm looking for a P59 PCM with IAC drivers, Flex fuel enabled, and 2 bar Real Time Tuning. I 'think' I can find this PCM on 2003 Tahoes, Suburbans, Yukons and Yukon XL, with this service # 12576106, and this hardware #12570558. When I find these PCMs for sale they have YCTJ on some of the identification labels, and YCTK on others. Does anyone know what these codes refer to? Thanks for any help you can offer.
    Mike
