I don't like the look of that clamp on type probe.
the one I put on my truck I drilled the manifold. I didn't have any problems with chips in the turbo. I didn't use a vacuum or grease..just lots of drill bits. I started at 1/8" and used every drill bit(1/64") step upto the right size for the 1/8" pipe tap. then I cranked the engine..not so much as to start it..just wanted to blow the metal shaving through the turbo.
just my 2 cents
