    JEEP 4.0L how do I increase rev limiter ??

    Can anyone point me in the right direction? I am trying to figure out this MOPAR JTEC PCM. it is alot different than the GM stuff im novicely (is that a word?) used to.

    im building a 4.0 stroker (4.6L) and not cutting any corners. ie. not a budget build. So I am looking to (mostly) maximize the tune and therefore power.
    current build: 2000 Jeep Cherokee XJ, 4.6L stroker w/mild cam, competition ported Newcomer Racing head, Hardland Sharp rockers, full 3" exhaust, 62mm TB. 24# injectors etc..

    LS6 swapped Porsche 944
