are you using a blow off valve or a waste gate? either way you need to up the spring pressure that controls the valve to gain boost pressure. some are adjustable, some are not and you need to replace the spring.

my mind is aglow with whirling transient nodes of thought careening through a cosmic vapor of invention.
