I have the Greddy Profec Oled. If you're seeing 14.5 with the EBC off and not wastegate , theres a problem with your plumbing. The Greddy is like Voodoo magic to set up and I wouldn't bother it if you haven't figured it out yet. Plumbing is a different story, scree that up and you will guaranteed pop your motor. It's a $15k exercise and you don't get a tee shirt.
