Adjustable boost elbow settings ?

Just finishing up installing the 4000GSK, 60 lb valve springs, #10 fuel plate and guages and timing bump to around 15.5 degrees. The adjustable boost elbow as well. Where should this elbow be set at ? Does adjusting the boost elbow from one point to another mess with any fueling or anything else? What I mean is if I adjust the allen screw does that require me to adjust anything else such as the idle or anything? Thank you . Cant wait to drive it and see the difference

on a stock turbo, just set the boost to 35 psi or less, i would bench test it though, some boost elbows, if adjusted wrong, can actually cause the wastegate to stick open between shifts

Adjusting the boost elbow will only adjust wastegate opening pressures. It may increase your fueling if you get additional AFC travel due to higher pressure, that would be it.
