I turned the boost up to 10-11psi and tuned it tonight then turned the boost down one click. This type of boost controller doesn't hold rock steady; it slowly floats +/- .5psi at peak boost. I knew that might be the case when I went with the bleed-off type boost controller. It doesn't particularly seem to be a problem. This might be the result of the ball/spring setup in the "T".
MAF counts are peaking out around 900 at 6500 RPM at 10psi. That's 20 counts up vs. the 12psi of the IHI turbo. It's safe to say this flows a higher CFM.
