Hello All,

I am wondering if anyone can tell me how to perform a Boost leak on my N55. Per this data log Protuning freaks is recommending me to do the test. I have Disassemble the charge pipe and the intercooler in multiple times to ensure that all the O-ring are in place and in good condition, but I still have the same result.
I purchased the Boost leak tester.

You can also make one yourself with a PVC end cap. Drill a hole in it to fit a valve stem from a bike tube. Then use an air compressor to pressurize the system and watch for leaks in the pressure gauge.
