Hi Tom,
It's possible that you will still ping with 91 octane under load but in most
situations you should be okay. You'll be more susceptible to it during the
winter formula months. There are ways to overcome it...at least I did with
mine.
1) Use Autolite 3923 plugs..I gap mine at .045 during the summer and change
them out and to .040 in the winter, however I have an MSD ignition and SS
Blaster coil as well....so you'll have to experiment.
2) K&N Gen II FIPK
3) F&B TB
4) Mopar headers
5) Borla Catback Exhaust
I think all of those items help it not to ping. Make sure you also check
your belly pan on a regular basis. If it still pings after everything you
try your best bet would be to use the additives.

Subject: DML: CA premium fuel
I just ordered the Mopar Perf computer for my '98 Dak. The notes in the
catalog say must use 92 octane fuel at a minimum. I would be happy to but
all the refineries here in the great state of CA seem to have limited their
production to 91 octane.
Question for those that know: Is there any brand of gasoline now being
produced in So. CA at 92 octane that is locally available? I really don't
care about avgas or race gas, gang. Just pump gas that will work in my
truck
and not ping.
Secondly, anyone running a '98 or later Dak with the Mopar Perf computer?
Is
it really that sensitive to octane level? The Mopar Perf truck hotline guy
said it would need 92 octane or an additive like 104+ to get it up there.
