I was really scared to use the Baumannator after a few negative comments I read about it on the net.For a fully auto setup, the Baumannator offers great control and comes with a few files tuned for the Cobra. Check the Baumann engineering site for pricing and all the support items.
As far as WOT in OD; I don't believe the 4R70W will stand up to that level of power.
I still ended up using it and it is a GREAT trans controller. SUPER simple to use, they have some really good preloaded files and Kevin at Baumannator is awesome for tech support. He helped me every step of the way. I would HIGHLY recommend it. I would love to see what the new optishift has to offer.
