Since the factory fuel cutoff occurs at 1.1bar or about 14psi I don't see how increasing the boost to about 13psi is going to harm anything. If it was damaging to the engine then the cutoff would be at 9psi...... I say crank it up and let your engine run as it was designed to. If you are only getting 8-9psi there is a good chance that the IP is not fully increasing fueling or reaching maximum fueling under boost. Adjusting the boost to the maximum allowable factory spec should allow for maximum power without causing any harm. RT
