Fuel enrichment delay under power enrichment raise it to like .500 lambda vs .050 stock. Also you can go into transient fueling. Go to acceleration gain and multiply the whole table by 1.50. Transient is a kinda gotta play with it parameter but it helps with tip in fueling. Also what I found is if your upper air flow on
Your MAF is too low it will cause it not to go into PE
Could also be speed density is out of whack in the tune since those cars utilize it. You can also disable most of the mapped points and just tune with like the last 10 so it makes it easy
Yes, likely sd calculations, or torque model is off. Setting limiters too high will also do this
