Before I had mine on a cold night it sometimes would spike to 25psiMine is down on the passenger front next to the PCV catch can. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/88722-lowering-the-boost-to-safe-level-gtx3582r/page/4/#findComment-1485869 Share on other sites More sharing options...

Why not just buy an adjustable wastegate, surely they are cheaper?
