adjusting a t-25 wastegate

Is there anyway to do this? I was wondering because if I am going to run 6-7psi and the facorty setting is at 8 I was needing to drop it by about 1 psi. Then I figured in that if the pressure drop is 1.5psi in most intercoolers. anyways I really need some info on eclipse intercoolers and the t-25 anyone have any sites? I will go post this in a DSM forums too to see what they think (if anything.)

you can bend the wastegate bracket in
