bogging down
i have a 06 5.4 f150 4x4. I have no power in higher rpm’s. around 3500-4000 and it will be screaming at 4k but not be going anywhere and i can feel it bog down when it does. lower rpm’s are fine but when i get to the higher rpm’s. feels like truck is bogging and losing power. Have no clue what it could be i have no codes or anything, i’m also striathtpiped. but i doubt it has to do with backpressure. doesn’t send any codes as well as intake is clean and is also not collapsing
