I have a 2007 ls2 corvette that if I run it in SD mode and blip the throttle to shift down there a delay or lag for the rpms to come up. The log below is full of throttle blips and its alittle rich due to just flashing this tune to get this log.

It's likely a lean spot in the vve or ve table.

hmm ok. Ill have to try and find that spot but I was told when logging for the ve table to be smooth and not to blip the throttle
MAF in my opinion works way better for those transient situations. I run mine in SD but switch to MAF for inspection reasons here in NY, but boy down bottom seems to be so much more responsive with the MAF. (Installed card MAF in OTR intake and tuned it).
But as Alvin said, its likely a lean spot just off idle.
