I don't know where exactly to post this, I hope is a right place. I see eveybody instal boost gauge alone. Isn't there a benifit to have boost/vac gauge? I want to instal a boost gauge but then I came cross this boost/vac gauges. Any explanation woulde be greatly appreciated. Knowing the vac doesn't have any benefits?

You will never see the turbo on a modern turbo diesel engine go into a vacuum state.

The boost/vac gauge is usually used on gas cars.

You'll want a boost only gauge, if running stock turbo, a gauge that goes 0-35 would be a great fit.

Any recommendation on which one to get? Can I run one with my Banks sixgun also?

Lots of guy run the Autometer. I'm gettin the Isspro's . Check the vendor section and look at Dieselmanor's guages..:D Of course there ar other vendors that carry them as well.

Does anybody has a picutre of where to tap on LLY? can you tap into intercooler pipe? Does it give you a right reading? Picture really helps:confused:

look at kennedy diesel he has directions and picture how to.

and later get the boost/vac, LBZ's and earlier get the boost only..
the lmm's have a throttle body, like the gassers.. lbz's and eariler are open from the filter to the valves.
