So like the title states , Im overboosting. Seeing between 4-6, some times more , PSI than I should.

Started when I was down in Reno over the weekend. I am tuned by and OTS map from XPT. Only engine mods are TBE and Drop In K&N filter.

2nd gear can see up to 19psi.

3/4th gears have seen between 21-24psi....

Ive had a look at the BCS line that Ts off at the Turbo, left to the wastegate and right heads to the hot side. In the line that heads to the T from the BCS there is a little tiny cut , which looks to only be superficial, but could that be the source of my overboosting? All other lines in that area look okay but I am looking into just ordering all new OEM lines/T for that area from subarugenuineparts.com ... Just looking for some guidance since this is my first problem with the car since ive had it, likely its not major in the way of blown motor.
