I am looking for a little feedback in regards to using a HP WGA. I am planning on running around 28psi boost with a IX turbo and Aquamist. Running at WG pressure I am hitting 25 psi with the boost controller turned out all the way. The preload is set to medium, I have turned it out all the way although do not make any difference. Even put on a Halman Pro, same result. It just about makes my MAC valve worthless. Although, going from 28 psi to 24-25 is better than nothing. I will be installing a map switcher as well.

Who is using a HP WGA? What benefits have you seen over stock WG? Worth it or should I put the sock WG back on? Any feedback would be great!

 

Bump...

So no one with any feedback? How about info in regards to the FP WGA? I am looking for optimal preload setting running 28psi.
