RPMs in first gear

[Beecher]

My 2003 turbo is difficult to shift well from 1st to 2nd in that the rpms drop more slowly in first gear when I put in the clutch than in the other gears. I find that I have to wait longer to grab 2nd gear than I should while the engine rpms drop. This only happens in first gear, the other 5 speeds are fine. Why is the engine computer doing this? The tach drops like a rock in 2nd to 6th. Would a GIAC remap fix this? I came out of an M3 which was consistent in all its gears, not that I would go back! :D It's a small thing, but very noticeable. Any ideas?

I think this an emmisions requirement. Does it feel lkike the car is not slowing down as fast as should due to engine braking in gear? Almost as if there is a small amount of throttle built in?

If so, we can thank emissions regulation for this issue. Something about the car making less emmission if the throttle is not closed completely.
