38mm w/g will be fairly large unless it's making a fair bit of power, but will also depend on turbo etc.
But 4psi to 15psi with a good EBC shouldnt pose any real problems.
The EBC is well regarded from what I have read online.
The 38mm wastegate is fitted to a tubular manifold and a GT3076, the engine is a 1000cc motorbike engine and revs to 13500RPM. Last year when setup it was controlling boost correctly, but this time the manual boost controller was playing up, hence looking to swap for an electronic boost controller and lighter wastegate spring.
