2015 m6000 ctec2 hard to start, wont get rpm and bogging/misfires.

Has spark, cleaned apv valves, replaced apv actuator, replaced tps
Fuel filter is clean and sees no damage to wiring loom.

Any ideas?

Fuel pressure spec for the 2015 6000 is 58-62 psi so you are on the edge of the tolerance. You may consider rechecking with a calibrated gauge if you haven't yet? One other change made to the 6000 Ctec in later years was the addition of a damper on the fuel rail. If my memory is right it was more for bogging when you were off and on the throttle.

Stable pressure while running, doesnt drop when blipping the throttle, bogs/dies when i hit the throttle. Checked with two manometers, pressure seams ok..

It is the round piece screwed on the fuel rail #6. It looks like the damper was added in 2018.

That's not the first time i have seen that. Those are hard to track down. Glad you got it figured out and back on the snow.
