Spartan 250 tune shifting weird?

Ive been running the 250 tune for awhile now and its great.

One thing has began to happen often lately that is starting to worry me is that under 1/4-3/4 throttle pedal the shifting is funny.
It kinda sits and revs before it goes into the next gear. Kinda like bouncing off the rev limiter.

Also at cruising 80mph it kinda wants to jerk more. feels like its stuttering along for a minute then goes away. I really dont know how to explain this more either. Like if you were pressing the go pedal letting of pressing letting off repeadtly.

I hope these explanations makes sense. Any one know whats up with this or should I ask Matt directly.
Matt if you see this chime in bud. Its got me worried
Thanks

Just replied to you over at the Garage too BTW...

Catch up with us on Tuesday and we will have you take some datalogs. I'll be at Atlanta Dragway Friday and Saturday, so we can catch up with you there too and take a look at the truck in person.

This is why when I purchase a tuner it will be a Spartan.
