Accel enrichment tuning

Im having some trouble getting my AE dialed in.
I have a 13b rotory with 50mm ida style throttle bodies. I expect some bug from the big throttle bodies, its been a while though so I dont really remember how much is normal.
The fuel map dialed in fairly well though on the rich side(on purpose).
roll in throttle moments are ok. If I stab and hold it hesitates quite a bit before continuing to rev.
I also notice while Im cruising when I first tip in i get a hesitation.

Im lacking in experience so Im not sure what to do

Agree with elturbonitroso.
When you stab the throttle, the active map point is going to move in a vertical direction. The table values in that area won't need to change a great deal because of MapMultiply
The Accel enrichment setup in my tune is just a straight line, starting from 0. You might also want to check a data log to check when AE is activating, the TPSdot threshold might need to be looked at

Turned out I had a different issue casing my problems.

If your brake booster check valve goes bad it causes all sorts of wonkey issues while tuning. You'll notice it in logs because your map signal will taper gradually when throttles close instead of quick drop off.
