Help: truck shudders in tow/haul mode

I was using my idp tow tune and was towing a 8k trailer. I was in tow/haul mode and would experience a bad shudder between 4th and 5th gear. I would have to let off the accelerator for it to stop. If I took it off tow/haul mode it would not do and shuddering. I have towed before with my tuner and in tow/haul mode and never had this happen before so it was very surprising. Is it possible that the tune dident load right when I switch from street to tow on my tuner? Or if its axel wrap why have I never experienced it before towing the same trailer? Anyother possibilities anyone can think of?

I just towed my trailer this weekend, Its a travel trailer approximately 8k with my 08 F350. I have the spartan tuner on 210 tow tune and experienced the same shudder at approximately 60 mph when I attempted to pass a car on the highway. Not sure what it was but scared the crap outta me!!! I had to let out of it to get it to stop. Im curious to see what response you get, sorry I didnt have the answer.
