Bucking at WOT on hills in particular

[speeddemon31176]

Hey guys I am having an issue of the truck bucking at WOT which is noticeable on hills without a doubt. I haven't felt it buck on flats but it does seem to run out of steam at a certain point. I have no light on for codes. I did just replace the fuel bowl and regulator assembly from Ford as a unit with new harness and while I had the valley opened up I cleaned the hell out of it. Right down to original paint on the valley. I have noticed a very small amount of fuel right under the fuel pump and I did replace all of the lines with approved lines and fuel injection type clamps. The lines/bowl assembly-regulator are not leaking. I felt all around the banjo bolt assembly at the back of the fuel pump and no leaks there. I also only have about 40-45 psi at idle. I have not redone the bb mod since installing the new bowl/fpr. Does it sound like the pump is dying or am I overthinking this? Thanks for any and all help with this.

Side note: I do have a very tiny amount of oil showing in the ICP connector. I did the blowby test with the oil cap and it doesn't lift off the opening but there is blue smoke venting out of the engine when you take the cap off.
