Different kinda shudder

Im having an issue. With a trans shudder but im hesitant to belive its the trans. Everything is as u see in sig. Trans has about 60k and regularly serviced. With xzt on power mode. Around 45-50mph light on throttle I get a shudder( like somebody shaking you not lock unlock). If I flip xzt down a notch it goes 95-100% away. Or if I push throttle little further it will clear up. Seems to just be at that 1250 1300 rpm mark. This problem just came on all of a sudden after truck sat around for about a month while getting painted. I've towed about 4klbs with it and problem was no worse just the same. Thanks for any input on what to try.

Sounds like my truck is doing the same thing but I have the 6spd. We have the same chip and mine will act the same when I flip the clip down. I have tried all the APPS voltage and stuff and it just wont get rid of it. I just ordered a new Timbo APPS last nite and hope it will fix my problem.
