Crit, What exactly are you refering to when you said
"the new PCMs won't do me much good when (if) they're released for the 4.7.
Because you can't go back afterward" ??? Are you refering too a Mopar perf.
PCM, or the updated Flash from the TSB??? I realize once reflashed you can't
go back, but you can always swap your old PCM on right?? Are you having
Pinging problems now??? rough idle??? I had the rough idle when mine was
new, since then (22K now) I never have that problem, AND even with my Mike
Leach custom PCM with 5 degrees advanced timing I don't get any ping, never
tried 87 gas, I have tried 89 before, no ping.
I'd recommend Mike Leach, he can fine tune the PCM just like you want it,
whatever advance you want, or fuel curve increase, totally custom, and if you
don't like it, he'll put it back to stock and refund your money!

<< Alright, I snagged this info from moparchat. TSB 11-023-00 involves
reprogramming Daks, Durangos, JGC with the 4.7 to fix the problems listed
below. I imagine that, along with a few tweaks, it retards timing at WOT. I
don't know if this is a new flash or the same one that others have received,
but I don't remember seeing the specifics before. Personally, I'm looking to
make as much power as possible while having no ping and stick with 87 gas, so
the new PCMs won't do me much good when (if) they're released for the 4.7.
Because you can't go back afterward I'd like to find someone that's done
this.
Do the new flashes have a noticable drop in dyno runs, butt or otherwise?
I'd
prefrer a little ping at WOT through 2nd and 3rd if the alternative is
putting
my 4.7 on no-doze. Anyone have thoughts or numbers?
It will address the following symptoms:
1.) Part throttle or wide-open throttle spark knock
2.) Sag or hesitation following a cold engine start
3.) Rough idle
4.) Idle sag on deceleration to a stop
The TSB involves reprogramming your PCM with new software (99Cal20 and
00Cal17)
