Raising UT will bump up boost at all engine speeds. Going up a stage will only raise boost above ~5000rpm. So it really depends on what you are looking for. Usually, we like to keep a self-imposed torque limit in place which means limiting boost to ~13psi in the low end. Or else we would see the 400+lbft peak torque situation that isn't really necessary.
