Roberto's white 930 was the car that was running the Andial (Craig...I think you know him). The day we were on the dyno he made ~400 hp at the wheels, but with a very rich afr. Off the chart in the mid range...
The solution that Dan is using sounds like its working in a similar fashion. Its just smarter how it chokes off the control pressure to get the plate to move easier. For that matter, the Leask mod is doing the same thing. It sounds like its using an rpm delay on the boost signal to kick in the WUR for on boost enrichment. Its certianly another way to get more fuel based on RPM instead of just boost.
