I got a gryphon in early sept and have the EXACT same issue. i thought it was coincidence, but it only does it on SETTING 2 / 87 economy tow. Drivability is crap. I had to turn it to setting 1 'tow only' or 'shift only' or whatever its called.
at this point it looks like this is a known issue with the canned #2 tune, not a couple coincidences. Good thing I found this, I was just about to start throwing parts like coilpacks at it to solve the issue.
I guess its time for a ticket for me then. btw...2006 fx4. is it just me or is this a lot of 06 models?
