Ever wonder if you have a boost leak or you know you have one, but can't find it? We finally have the tool needed to locate all boost leaks, no matter how small in minutes. This is a great tool to use anytime you have opened the system for anything. Even the smallest of leaks (1-3lbs) can cause tremendous loss of low end, slower tubo spool, and higher EGT's. Simply connect this device to the inlet of the turbocharger and pressurize with a standard compressor to 10 psi to 20 psi. You will hear even the tiniest of leaks in seconds.
