looking good, problem is when you let off the gas, even if it is slight, ECM
starts pulling out full via the INT, this morning it dropped as low as 40.
Then when you get back on the throttle, INT is low, hence fuel is lean,
truck stumbles, until INT climbs back up to 128 or somewhere around there.
> Looking at the BPW calculation (p4 doc.) is show the DE term is multiplied
by the others, the DE table has values from 1.5 to .75.  I have reduced them
some, but didn't see any improvement.  Maybe I didn't reduce them enough, or
maybe I need to change something else, as to put it in decel with less
throttle change.

On my GN, I set the DFCO enable, to 254dF.
I like having some EGT to be able to spool the turbo, after lifting the
throttle.
