The Pop-Off valve is essential on all turbocharged engines. It has to be installed between turbocharger and throttle, the best position is between throttle and intercooler (if present). Pop-Off has the task to open to discharge pressure you have into intake manifold when you release accelerator. In fact, when you raise your foot from accelerator the turbocharger keeps on fast spinning pumping air into the line (that results closed). To avoid damages to turbocharger, you produce - by Pop-Off valve - an escape for extra pressure (useless in releasing).
