For under boosts I go by a smaller value(2-5%) because as you increase the value the percentage increase grows each time. Increasing the WGDC adder table also works on under boost, but I kind of like using the base table.

My stock turbos are pretty healthy and not very picky so I haven't had to make a lot of changes. I have a set of TD04s on the way, when they get installed I have a felling I'm going to be spending a lot time in the WGDC tables haha
Good info, thanks!
