Why is it...

From a 40 roll, when I stab the throttle, it drops a gear and I can see the KR spike to 10+ degrees. I let off after a second, but not more than two.
BUT...
From a stop, or even if I'm already moving, if I roll the throttle to 100%, I can run all the way up to the shift with less than one full degree.

Current mods:
E85, 1;9RR's, Headers, 3.1" pulley. The only thing engine/fuel related I changed in the tune was scaling the injectors for E85.

Can someone explain why aggressive throttle entry would cause so much KR, but slow(er) entry would cause almost none? Just looking for knowledge.

Thanks.
