Works perfect for boost leaks.
Worked great and found several boost leaks on my 2012 ram 2500 with s368 turbo. Just buy it if youโre questioning yourself like I did. lol

Worth it! Buy this one
I used a little pipe dope to put the gauge in the cap, but it might not be needed. Clamps feel good quality, it fit snugly together and perfectly in my 3rd gen swap 4th gen 6.7 Cummins. This was exactly what I needed with the angled valve stem, that was a game changer as space is limited but I found several leaks and fixed my issue. Good quality for a fair price, easy to assemble with no leaks. Iโd definitely buy it again if I lose this one.

Worth it
Does what it promised. Found all sorts of boost leaks. Cost me a lot more money due to the parts I had to replace ๐คฃ, but brought back a ton of power.

Good unit, outstanding customer service
This is a well built unit. I did not read the description closely enough and this one doesn't work with the 2002-2006 duramax as it has a smaller piping. Their customer service was above outstanding ( real time texting) and got the adapter I needed to me fast. Found the leak, lower passenger side of the intercooler.
