The Sn89 on my car now only pushes 1 pound of boost at 3500 and at 4500 its like 3 but peaks at 5800 at 4.5 . I dont want more boost I want earlier boost. Not like a roots I know.. but it should make some boost sooner.... 1 psi is horrible. Ive checked everything to see if Im losing boost and its all good. Im ready to sell this thing...
