[QUOTE="KCTurbos, post: 1248299, member: 13852"] I saw this thread earlier today... but did not respond... so I had all day to wonder about it. So sorry for the long post. What is your max engine load at WOT? What is your max fuel desired at WOT? You might not be reaching maximum fueling parameters for some reason... probably like you mentioned it has something to do with the MAP sensor being bad? Or i have seen issues with the diesel fuel parameters of the tuning section. There are some weird portions that randomly happen with some strategies that limit fuel parameters based on things like oil temp, boost, elevation etc... I would make sure your tuner has removed ALL fueling parameters in the diesel fuel section. What all did you change? Just the turbo/injectors? Does not make sense why the map sensor would read right for one turbo and not the other? Did you try plugging in the vgt solenoid and just let it dangle in the engine bay? I have heard of some strategies that will cause issues if it is not plugged in, but I don't think it is common. I know you said you have no boost leaks? But did you pressure test? I see cracked map sensor lines all the time that will only leak under WOT so you don't feel your typical idling boost leak. Possibly a PCM/wiring issues that is causing the MAP sensor to read funny. Possibly a bad BARO sensor that is causing a weird boost reading or altitude reading. [/QUOTE]
