Monkey, how would porting help? Its already ported which we think is the problem...The stock spring is like 7-8psi, but a 7-8psi spring starts opening earlier to maintain 7-8psi....With a ported wastegate, it takes less actuation to achieve the same wastegate venting so by the time you reach 5-6psi, its already opened as far as a stock gate at 7-8psi.
