Both the XP and the NIC bleed a lot of boost off but it shouldn't be that low. Is that like a steady 8 psi WOT on the 3.1? Is it like 8 almost 9 Or like barely 8?

From my understanding you'll see the valve float in the higher RPM range, like 5700+. Where are your shift points? Got any scans, like a torque log for us?

I'm guessing from your post you're not sure what the boost levels were at previous to now. Like how much with your last pulley on, before the 3.1?
