Just got the new MSD lazer guage...pretty cool but i need to know where to tap into the boost side to get an acurate reading???? where have most of you guys done it? I have a 2002 LB7

Thanks a million!

If you do a search, there are a couple of methods that work well. I chose to drill/tap my intake manifold. If you look on Kennedy's site (www.kennedydiesel.com (http://www.kennedydiesel.com)), there are some tips and pictures that really helped me.

LB7 SD Manifold

2001-2004 LB7 SD manifold for the Duramax. It replaces the upper I/C boot just before the engine intake manifold. This provides a means of running a boost sensor, water/meth nozzles or what ever you wish to plumb in with out the need of taping the engine manifold or I/C tube.

I started out having a plastic T in my wastegate hose and it gave a good reading but it wouldn't stay put when the enging boost got high, the tube would blow out. Ended up drilling and taping the passenger side intercooler air tube and no more problems. There are some pictures on this forum if you do a search.

Ditto on the Super Diesel manifold, it's very nice piece.
