So you're using the computer controlled boost and you are pretty sure it has FWD Performance computer?

There are WG adaptives that would try to get the boost in line with whatever the programmed goal is, but they can only do so much.
How much do you want to run? Remember, you can always put a full signal to your WG actuator to get minimum boost while you try to sort things out. Then a quick manual boost controller in that line to start raising your boost.
Suggestions if you really want to use computer controlled boost- if FWD-P computer you could contact Cindy for Cal options, seek out any other provider of calibrations, or start working on tuning it yourself. Seems that most don't want the "hassle" of working with the computer controlled boost, but it does work well when it is set up.
