Pros of EBC: Often has boost monitoring/gauge Easier to tune pressures Less boost "creep" Able to tune RPM vs Boost to reduce wheelspin (some types like Apexi AVC-R) Gizmo factor / another toy to distract you from the road
Probably it would be OK as long as you have some way of monitoring your boost levels (ie: boost gauge). You wouldn't want for your valve to come open and leave you with unrestricted wastegates (only fun for a short time)
