Bypassing the overboost solenoid was def part of the problem. I saw 13psi for the first time today. I need to go back and check but that might also be the max range of the bosch boost sensor.

According to this, I should be good to 3 bar... http://www.superturbodiesel.com/std/Thre...4#pid55954, I think I need to hook up an analog boost gauge and verify my digital. IIRC the overboost doesnt kick in until 16psi....
