Jez sets up the boost controller to reach the require boost for mapping, i found i needed to tweak it somewhat to keep it in the safety margins when running my high boost setting. My low boost setting comes in at 0.6 Bar and limits at 0.8 pretty much like stock and is what i use 80% of them time driving.
