    There are limits as to what you can change a value to, sure you aren?t at the limit?

    Looks to me like 110.3kPa is the limit you can raise it up to.

    Curious as to why you see the need to raise baro axis above 110.3kPa, you will never ever ever see that kind of barometric pressure.

    would help being more specific to which table you are talking about. Like Pilot Timing Baro Correction Multiplier table. I'm guessing the limit is 110.3kPa, which is like 16psi atmospheric, standard sea level atmospheric is 101.325kPa or 14.696psi, unless you plan on driving well below sea level, what's the point? If you want it at 206.8kPa at the upper end and just must absolutely must have it there no matter what, you'll probably have to get user defined parameters and adjust it there. FYI, pull a hard run your turbo will actually cause a drop in barometric pressure reading from the suction of the turbo inlet, for what it's worth.

    Your rpm limiters are holding fuel back, it's calculating fuel derate being setup at stock values. Your main pulse limiter is still set at default. AT a glance, your pedal map is still at default. Rail Pressure appears to be at default. Just a few quick observations.

    Really know nothing about your truck so can't really say much.

    Do you know how to increase or change cylinder pressure? Not to be rude but you shouldn't just jump into tuning something if you don't understand it. I wouldn't jump into the ring with floyd mayweather without first having some sort of boxing of skill. You need to spend time learning how a diesel engine operates and then really get to know the tables on you ECU and start finding correlations.
