240sx bogging

[tman6500]

Mods: cat back exhaust, stage 2 clutch and light flywheel.


1995 240sx the car idles fine and under slow acceleration the car will rev up
but any acceleration past like 15% throttle the car stocks bogging really bad
and will die if not brought back to idle. No check engine light on. Last thing
changed on the car was the clutch and flywheel was about 4 months ago.

Things i have tried cleaned the maf,replaced fuel pump and filter,replaced plugs and wires,check ohms on injectors and pulled plugs off one by one but made the engine get worse,checked for vacuum leaks,checked fpr, hooked up fuel pressure gauge got 40psi idle 50 55psi when bogging, pulled exhaust off and ran just headers to see if the cat was clogged.

Any idea would be helpful
