Transmission Strategy TQJF4 and Experiencing Surging?

OK now after driving more attentive and monitoring my mfdsd closer on the livewire and feeling the transmission shifting I've noticed that it only happens in one of the gears and I believe its third gear; and the rest of the gears if I let off the accelerator I don't experience the surging or drop in the mfdsd. Now I have looked on the site and they added the TQJE5 strategy but my transmission strategy is TQJF4 so I'm thinking that its not the engine tune but yet the transmission tune that is causing my surging. I have spoken with the tech support both james and rudy and gave them both what I am currently experiencing with the tune and supplied them with both my engine and transmission strategies along with my engine and transmission #'s. And they said they would get back to me as soon as they do some testing.

I know I have posted quite a bit on this topic, but is there anyone else that has the same transmission strategy as me and is experiencing the surging that I have been talking about?

Is it that no one has my transmission strategy or is everyone running their tunes just fine. Is there anyone that their build date is 02/08 or later and if so what is your strategy codes; and are you experiencing surging while 1.20 or 1.22 is loaded.

I've never seen one with that strategy. I'll programmed a bunch of these 6.4's the closest I've seen is TQJE4, sorry. It works good in that one.

I asked SCT on their livechat if they had an archive of their tunes and was able to see if my transmission strategy has been covered in any of the tunes released so far. Just curious if anyone knows if mine has been covered by any previous tunes? I've googled and haven't been able to come up with anything.

Well today I loaded up the extreme tune for sh!ts and giggles, but what I did differently was use the tow/haul and now when I let off the gas there is no surging, but while monitoring the mfdsd it still drops down to 0 in the 35-55 mph speed range. Anyone have a clue as to what might be going on with this tune and my truck?
