Running code $59. The car runs good but I have an annoying thing I would like to get rid of.

When I hit DFCO lower limit 1000rpm the rpm starts to hunt while coasting (1500<->1000rpm) until I hit DFCO mph disabled.

My guess is that the BPW the engine gets when it going out of DFCO is to big...

I have played with everything I can think of but its still there.

any ideas?
