I'm attempting to do some transient fueling tuning on my car. This is an LS3 Corvette with an ECS supercharger on it, no other mods. This is a MAP only tune. In an attempt to get rid of a lean spike I kept turning up the Impact Factor Gain.
I'm doing a low speed 50% throttle blip to try to get things figured out.
I started out with this. A lean area where the throttle starts opening, but then it goes down where it should be pretty quickly.

After turning the Impact Factor Gain up to 1.0 I ended up with this. Same kind of spike in the beginning, but then a large rich area when the transient fuel kicks in. Then back to where it should be.

Any thoughts on what I can do here? or where I should be looking for a problem? Any advice would be appreciated. Thanks.
Here is the starting file.
