Rough acceleration from 2-3K RPM only in 2nd gear

Hello all,

I have a strange issue with my 04 TSX 6spd. With a cold engine when accelerating from 2-3k RPM in second gear the car hesitates\stutters quite a bit; if I go beyond 3k rpm in second gear it completely smooths out. This clears up about 75% when the engine warms up but it is still somewhat noticeable. This RPM range is perfectly smooth in all other gears.

Any ideas? Tried changing the APP sensor and I've done quite a bit of maintenance recently such as changing the spark plugs, transmission fluid, serpentine belt, etc as well as installing a CT icebox and Hondata reflash. Note that this issue existed before these "mods".

All in all its not a huge deal but if there is some fix I would like to take care of it.

Thanks
