Thank you everyone for the responses.  I always inform my customers the
advantage to disable dod and most of mine already have a disabler plugged
into the dlc.  Im near San Antonio Texas and it seems most of these country
customers already know about the engine failures.  Most of these people
commute to SA so most put 30 to 60 miles one way to work.  They hit
terrible traffic once they get close to the city, its mostly small hills
and long stretches of some what flat roads. The reason i started tuning is
because i had one truck that had cheap mounts in it from AZ or Orielys and
after overhaul in dod you could feel that crap in the truck real bad, those
mounts suck, i always install oe mounts but since they just had another
shop put the aftermarkets in i fixed it turning off dod.  Then i had a
florida billet shudder out of the box, so i tuned it out.  then another
florida came back with a shudder, tuned that one out too.  I haven't bought
another florida since but installed at least 10 total but back to only pnh
billets, still never had a comeback of pnh, all units get either reamed tcc
reg, or zip kit and sometimes if bore is still good transgo valve.  I have
had success keeping dod at 20 rpms slip instead of 40, didn;t feel much.  I
typically don't mess with pressure.  When i zero tcc slip in V8 mode, it
will slip enough and bring it close to zero where i don't feel anything
abnormal and no complaints.  It will not hold zero slip like when you block
the valve in a 4l60e. I do agree though, small changes are a big difference.
