Car not going past 5000rpm in drive

[Aapanju]

Hi
I have a 2010 Toyota premio and only 40k km driven.
Car accelerates fine and shifts gears fine but when you hit the peddle under full acceleration it goes up to 5000 rpm than bogs. Won't go over 110km/hr but but if I let of the throttle it will shift gears and speed will go up as long as I am. Under 5k rpm.
Changed spark plugs and air filter.
Changed fuel pump (not entire assembly only pump)
Check catalytic converter and exhaust all ok
No engine check lights etc..
Any ideas what could cause this?

Thanks

Check your fuel pressure and fuel flow rate (L/min). You may have a kinked or collapsed line. See how it compares with the spec.

All checks out fine... The car accelerates perfect till 5000 before bogging.. Mech says transmission which seems unreasonable. No grinding shifts smoothly... But moment I floor the pedal it'll only go 5000rpm and abou 80kph...if I let go it'll upshift and increase speed.

Weird issue.

I also ended up changing entire fuel pump assembly but no difference...

Your ECT button limits your rpm. Try accelerating with ECT enabled.
