1kz-te loss of power on acceleration

[yurp9]

My prado accelerates very slowly and slows down drastically when going uphill even with the pedal all the way down. Injectors and fuel filter has been replaced, and turbo was checked to be fine. I'm thinking it could be the map sensor or SCV, but if anyone has any other ideas on what to check please let me know!

Check your MAP sensor filter. If your MAP sensor filter is clogged, your MAP sensor won't be reading pressure and thus your ECM won't let you have enough fuel.

Well, I have had such an issue before... still having it, did some research seems like it's SCV. So I advanced the injector pump timing abit.
