quick question about PE and fuel trim cell

[Cool28]

Read up on it but I want to get more info since the tune is a Speed Density tune. I have a 0411 pcm with a custom 3 bar program in it. This is running a lq4 408 and f1a at 12psi. When coasting after a few seconds the advance will drop to zero o2s will basically read very low 100 to 0 and the fuel trim jumps to 22. Now if I read up on that right that is PE kicking in for some reason. If so I went to the cold PE enable tp% and it is set to 2. I looked at a old program from a old motor and maf program and its at 60% till 3200 then 35 the rest of the way up.

Am I right in thinking that since the cold pe mode tp% is so low when I coast and tp% is above 2% so it jumps down into PE mode and kills timing and gets way rich? I looked up the ve table and it should be commanding 30 in timing and it does when its not in this fuel trim cell.

Any help would be great cause this is making the car not fun to drive.

Well that wasnt it. Put the value up to 20% and still does it
