Since you're a tech at a dealer (Dodge I presume), you should then know
that no two identical trucks run the same. (Thank DC for that
screw-up.) As for the performance, the time you posted is pretty
respectable for those mods.
Little screwy facts:
Dodge Dakota R/T - Run regular unleaded fuel
Dodge Durango R/T - Run Premium Fuel (Don't believe me...check the
owners manuals on both)
They're still based on the SAME 360 as in the Van and Ram trucks
(ok...and Durango's). Nothing fancy about the 360 anyway...it's a
workhorse engine unless you alter the internals (aka: Stroker Motor).
The 20-24 degrees is fine for WOT performance and it does slowly raise
to about 28 degrees at 4900-5000rpm. (Checked that with both my laptop
and scanner on a '99 R/T - Supercharged though.)
How did you check the mixture to verify that it's not leaning out at
higher RPM? (Simple question...nothing else.)
Now, getting to the point of feeling "dead" while driving, if you're
referring the sluggishness from idle to about 2400rpm, well...put a 2400
stall converter back in and that will be fixed. 2800+ for the street us
just plain silly.
Also, you didn't mention anything about a modified throttle body. All
those mods and a stock TB is really holding back that engine. Average
gains from a Flometrics Billet TB (on an R/T) is about .2 seconds
quicker in the 1/4 mile.

Subject: DML: "Advanced" question for the experts
While helping a friend with his R/T that has numerous bolt-ons( MP
PCM,Headers,Cam,1.6 roller rockers New 2bbl MPI intake,FIPK,MPRB?
exhaust,180 stat.,high stall(2800)convertor) it doesn't seem to work as
well as it should(99CC,14.2s at 95 I think is the best on slicks)I
noticed one thing that disturbs me. When you drive it, it seems kind
of"dead" ,sort of like not enough ign. timing. At WOT its only getting
about 20-24 deg. timing depending on RPM(using a DRB3).Now to ME this
doesn't seem like enough. I would think at least 32deg. My STOCK Jeep
PCM gets 28-31!!(it rattles on 91) I checked another MP one,98 5.2 ones
and its the same. All these guys can run 87 and they don't ping.Any
thoughts?? What SHOULD this thing run?? Are there alot of R/Ts with
these mods running quicker?? Not alot of these up around here where I
live.Oh and moving the cam timing around helped little,and its not lean.
