A valve body is an option with your trans and a very good one to use with the edge juice as that programmer does nothing for your transmission. The 1211 code is fairly common in tuned trucks actually and in most cases wont hurt it

Yes, the Juice can be changed on the fly, so that is comparable to chip operation as I understand it. I have only had a couple of issues to date. When I am not towing and I shift into 5 (extreme) I have all kinds of power, or at least as much as I want or need, but it immediately shows (throws?) a code P1211 (or at least the SES light comes on...I have since learned that it's a code P1211). I understand that I can spend a lot of $$$ and fix this with a fancy oil pump. And, it seems to have put my Lie-O-Meter out of business, which is no great loss. It seems to be stuck on 11.5.

My EGT, even under the extreme towing conditions mentioned above, have never been over about 1200 and seldom that high. Don't know whether this is good or bad.

Still open to advice and ideas. Thanks much, this is a great forum.
