Anyone Had Slow Shifting Adding DCI?

So I installed bms dci's a couple weeks ago and I've noticed something strange with 2-3 and 3-4 upshifts taking longer, sluggish, delayed, not as positive - I'm not quite sure how to describe it. It didn't do it immediately after adding the intakes - seemed to slowly manifest itself as the ecu adapted. I haven't changed the upshift softening in the procede so I don't think it's related to that in any way. Has anyone else noticed different shifting behavior after installing an intake? My 1/4 miles times improved, but the way it shifts now would make you think otherwise.

Mine just shifts slow all the time, even before the DCI's. So no I have not seen any difference in shifting after the DCI's.

Check to make sure you didn't knock a vacuum line loose when installing your DCI or cause an old hose to split. The DCI should have no effect on your trans at all.
