First, you'll want to post up some details of your set up;
What kind of boost level, fuel supply, injectors, ignition, what kind of spark plugs?
Is this a new build and this problem has been there since the beginning?
Or, is this a tested setup that just started dong this?
All of this will allow someone to give some kind of help.

First, it seems a waste to run a 6266 at 10psi.
That said, while not impossible, it's less likely that an ignition or fuel supply problem would show up at that low of a boost level.
I think it is much more likely that there is something with the tune, such as a boost cut setting is low enough that it is kicking in when the boost gets to that level. You may not experience it in lower gears because the load is just below the threshold.
You should run a data log and see if you can identify the specific condition that the symptom occurs.
