It is - for sure, but the only times I have had pinging problems was for
the first coupl emiles after I first programmed it - - I had 87 in there
and set it to 93 when I filled up with premium - and after a mile or two
it stopped.
Other time was under heavy load when towing. Had 87 in there with the
87 tuning setting, and it pinged until I put 89 in there and then all
was well. I have zero complaints about my power programmer and lots of
praise for it.

I checked the belly pan gasket and it looks pretty good to me. Josh
looked at it at the BBQ and said it was cleaner than his.

The 5224 is the plug that the books specify for the Ram 360?

Again the family series was 522x - not sure if thats the one you are
talking about - but as others pointed out and as I discovered there is
no 5223 plug.
I changed the cap and rotor - and I think I discovered what was causing
the misfire. The terminals in the cap had a nice layer of white
(carbon?) build up on them. I could have cleaned the terminals off and
reinstalled the cap - as they didn't seem to be that badly worn down...
I have sure seen worse. But with the cost so low - I figured may as
well replace. The old cap was a Wells... aluminum... the new caps and
rotor is the Duralast Gold brass cap and rotor (previously sold under
the Conrad name)

I have been meaning to put in a 180 thermostat... however all the crap
that seems to be above it (alternator, AC compressor lines etc) have
deterred me from trying. The Ram is going to be put back in the garage
for the winter pretty soon... so I'm going throw a lot of tender lovin
at it over the months its going to be mothballed. So I'll a thermostat
it to my list. (Needs radiator hoses, coolant flush, trans pan gasket,
all new front end suspension parts, some body work, yadda yadda yadda...
