sounds about right, If you install a boost elbow into your turbo, it will increase you boost 35 is the max a holset can take for reliability reasons.

According to my edge Juice monitor I can hit #35 of boost no problem and I'm running my Smarty on SW#3.

you can hit 40lbs if you try hard enough, I would say 35#s on a somewhat regular basis being the most you would want to see if longevity is your goal.

I have an adjustable boost elbow set to 32psi. The extra boost will keep the EGTs down. I'm seeing a little over 1000 degrees with the SMARTY set to level 7.
