So you are running both a "FMU" for boost and a adjustable FPR for idle?

Kris-

Yes. Everyone told me that once that walboro went in it would be too much pressure for the stock regulator. That's why I changed it out to a aftermarket. But honestly when I checked the plugs on the stock fpr they were fine not to black or anything like that

Plug checking is not a very accurate measurement device at all , it may be somewhat acceptable for small non performance engine . But not for a turbocharged vehicle by any means .
