fuel flooding

First test is to run with boost pump on low and see if this helps.
You need to go thru the fuel flow / pressure measurement / test per TCM.
My guess would be the barometric controller that governs the amount of fuel based on the upper deck air pressure. It is a closed loop and is probably the fuel pump or the controller.
Just out of curiosity did you try running on one mag while airborne to see if this could be a problem or at least eliminate a potential problem?
Do you have a jpi to see if there is one or two cylinders causing the problem in flight (roughness). Roughness is usually caused by an inbalance of fuel to cylinders or a mag(s) problem.
fyi
