Boost will not matter that much its how much power it makes at that boost. Back to my 1.8T days i ran 24psi on stock turbo and 24psi on upgraded GT35R turbo the power difference is nigh and day and i ran the risk of blowing the motor. So are you saying increasing the boost by 4-5psi on a stock turbo N55 motor it will blow? Aren't the N54 guys pushing close to 500hp on stock engines.
