60-1 turbos are very very capable of power, i'd say you have a small boost leak or similar, have you done a diagnostic? (located in the faq section)
how does she feel on acceleration?
by going with a larger compressor you are gaining the ability to flow alot more air which at the end of the day = more hp
when i upgraded to a mere 46 trim oh baby i felt the difference, it was awesome
once you've done a diagnostic and verified you have no boost leaks get back to us and i'd be happy to help further
