I did the 1.0 housing and the the wicked wheel 2 at the same time and I love the combo. I'm on stock injectors and I see 2-3 psi at 1300 rpm if I roll into it slowly. I noticed a huge improvement in in-town drive ability and it spools insanely fast. I can smoke my 35s on dry pavement in a hot tune. I max out between 23-25 psi up from 21-22 with the fully stock turbo but I think I have a slight up pipe leak that I'll be fixing when I swap trannys. I saw a pretty good improvement in mileage too I went from 13 to 15 and that's almost all spirited town driving.
