I recently put a stage 1 tune on my car with the Accessport and WOW what a difference in power. However, when I'm changing gears in the power band, i feel like the gas pedal sticks a little, you clearly hear the revs hang when shifting. Is this a tune issue? I put the non tps map on.

 

I've had this problem since installing mine as well. I've yet to find a cure for it.
