I played with it briefly once on my LLY. One thing I noticed was when I set a boost level in the staging table, when the boost built up to that amount, it would open the vanes and dump the boost. Don't know why. One thing I had mentioned that would be nice would be a RPM table so when you enter a RPM value, while DPS Staging is active, the engine won't go over that value until you take your foot off the brake.
