hey guys hopefully someone can help me out. i got a 2004 6.0 and it’s got no low end power it’s like the veins on the turbo aren’t moving but my exhaust brake works. so the veins aren’t stuck. i read on a different thread that the 03 engines got a flash that didn’t use the exhaust back pressure sensor so all i can think of is my map sensor. i don’t have any codes for a map sensor or a ebps or a turbo. it’s straight piped and the egr valve and cooler fell off.

vgt duty cycle is 0.56 at idle and it dumps smoke when you stomp it. ficim power is in range according to ford and battery voltage is at 13.47 volts boost will make 21psi max if i hold it to the floor and it will make it at like 3200 rpm.
