If you leave it at stock 7 psi and have some kind of fuel management to dump some extra fuel for the bigger turbo, it should be fine. Remember 7 psi on a GT2871R is not the same 7 psi volume of air off a stock T-25. If your going with an entalphy tune, im pretty sure scotts gonna tell you to go 740cc instead of 550s. Atleast thats wut he recommended me.
