Hello, I am wondering if I should get a Turbo XS Manual Boost Controller. I was looking to make a little more horse power and thought I could turn my boost up a little more. I have everything stock. And also, I got my self a Turbo XS Type 25 (RBV-25) BOV/BPV and was also wondering if it is a good one and if my Audi would work fine with it or should a get a Forge 007 Dv? Which one is better?

Thank You Guys
