UPDATE: James at Henson and I have been back and forth a number of times via e-mails and tweaking things for two weeks now.. Yesterday I bought a fully unlocked DD tune from him and I must say it'll blow away the tune I got from Bama. With everything now set to my liking as a "nominal" it's dang near perfect IMO. I told him I want to live with it for a few days before getting back to him. But in the one day I've driven it locally I'm very impressed. (I still need to play with setting and do some datalogging to confirm timing and A/Fs are in line)
Tell you what though, It's got POWER & the tranny shifts are spot on. The 1-3 skip shift is now tight, the shift firmness seems to be progressive. The more throttle the firmer the shift, and my WOT shift points are dead on where I want them for maximum 1/4 mile times & speeds. (yes I take it to the track
Keep in mind I'm trying to equip this ranger for long term ownership. So the shifts are not tire barking ones. But they are firm and the truck will jump fwd at heavy throttle. But yet.. at light throttle they are barely noticable.
At this point I gotta give James a "atta boy" for tuning my 06 FX4 ranger.
