You probably already posted about this, but did running open DPs increase or decrease performance or hp?

A little flatulent at idle, but pretty good revved up. The turbo keeps it quiet enough.

I'd like to see the diverter flap set up so one side is muffled, the other isn't, and it opens up at full throttle.
