Stage 1 will give you a max of 15.5 PSI as a factory setting. You should start at 15.
With the new Wastegate the Boost should increase very fast, so you will need to increase the Solenoid sensitivity ( That is what the old Profec B had) or anything that would make the controller react to the preset boost setting faster before overshooting the mark.
Once you have set it that there is almost no spike, continue to increase boost in .5 increments. I would say that it should be safe all the way to 16.5 but take it .5 at a time.
If you can get a G-tech or any other way of testing (Dyno time or at the track) it will make it a hole lot faster.
I used to adjust early in the morning with a G-tech Pro. HP figures may be off but they are consistent and you will see if you are increasing or decreasing HP.
