[QUOTE="PSD POWER007, post: 894067, member: 13870"] Man, with the WW2 on my stock turbo, I never saw back pressure over 38-40psi at 31psi of boost. It usuall stayed close to a 1:1 ratio. I'm very curious about tenants causing such back pressure. Even with the original WW did I ever see back pressure over about 40-45 psi at 27-28 psi on DP tuning when towing. And it usually stayed in the high 30's at that boost. Something is definitely off! [/QUOTE]
