I just did this and they installed the 446 pump and reflashed my Dinan.
I honestly don't feel any difference in performance, but I guess I got a new HPFP out of it (Already replaced it once at like 2,000 miles).
Dinan S2 was loaded back.
I still think I want to get a boost gauge since I think I've gotten used to the power increase and want to make sure it's not placebo. When I first got S2, I was blown away...now, it just feels quick.
