Default Idle issue

My problem is when I go full throttle for just a stab and get out of it fully, the rpms drop to about 500 and the engine has trouble staying running. It hasn't stalled ever, but it is right on the edge of it. When I give it full throttle and stay in it it runs great. Starts right up and has a steady 850 rpm idle in normal driving. Swapped the original TB for a ported one and used the original IAS and TPS and does the same thing. any ideas? It has no stored codes.

Add a two second delay to your follower air. Increase your follower air by 1-g/sec. Cut your follower decay in half.

That'll get you closer. If it starts hanging, just cut back a bit on the air adder
