There needs to be some resistance when you install the CP onto the IC. If it just "falls" on and you can rattle/wiggle it back and forth easily even once it is all the way on and clipped, its probably not going to be air tight.

I'm jumping from the BM3 v7.0 thread to here after confirming I have a boost leak. Thanks again for the inputs thejeremyman9. I created the boost leak tester you described in this thread and found a leak at the top of the coupler immediately. I tightened it down, tested to ~10 PSI (got nervous going higher), and ran another log. Unfortunately, the log was still junk (still on same gas) (https://www.bootmod3.net/log?id=5e8b...729b14ca1ecde9).

Did you have any problems pressurizing the whole system through the turbo inlet pipe to 15 PSI with this setup? I'm thinking about adding a pressure gauge in line with the cap because I'm not sure how accurate the regulator on my compressor is.
