Yep foreman at a Dodge/Jeep dealer.And you think those times are OK?? I
would have thought high 13s with those mods. He ran 14.4s-3s without the
cam,convertor,exhaust,rockers, MPI intake and FIPK(he had a cobbled up
homemade deal on it).

That seems low though for the MP PCM does it not???esp. when my stock Jeep
PCM goes as high as 31-32. BTW, this 99 MP PCM never went over 24deg.(at
wot)

I'm going by the O2 voltage,its about .90 at WOT

I guess I should explain that better.its nice and snappy,and runs fine, just
seems to lack midrange torque,and doesn't seem to start making good power
till about 3500 or so.
