Does anyone where you can get a boost pressure gauge kit?

My KW has a mechanical boost gauge from the factory, it goes to 80 PSI, if you have twin turbos you will need a higher boost gauge than I have, since I have a single turbo. I uses a 1/4" plastic air brake line rated at 200 PSI to the intakes side.
In a hard pull I can pin the gauge, but it usually is around 60 PSI so... whos boost gage is going over 80psi??

I'm from Ontario, Canada and we have a law that says all Class 8 trucks must be governed at ... 65 MPH. But I am pulling a dry van with 26,000 lbs in the box from Guelph, ON to North Carolina right now. I went over those steep long hills on i-76 east of Pittsburgh, PA without shifting while keeping an eye on the boost gauge. I had the cruise control set at 1,400 RPM (61 MPH with my 3:73 rears and LP 295 tires). The maximum reading I got was 42, which I understand isn't half bad.

I have Autometer gauges as well the C2 100 psi boost gauge less than $100 and then got another boost that is also a vac. gauge that is setup for the air cleaners to monitor vac pull on them and there pyro kit which is well worth the $199.
You get the wiring and probe kit for it and it's a 2 1/16" gauge so it fits factory gauge holes the pyro goes to 2000*f.If I hit that I think we have a problem. I plan on picking up a fuel pressure gauge next.

It does not see any boost I took out the filter minder that came with the truck that is on the alum. air tubes coming in from the air cleaners after the 2 meet and installed it there.It will only pull vac. when there is a restriction in the filters.
I never liked those filter minders because half the time they don't work.

gas turbocharged engines still do not have boost on the inlet side of the turbo; his vacuum gauge is for air inlet restriction.

I'm well aware of that... You install a vacuum gauge on the vacuum side of the throttle plate on a gas engine which will also see boost if boost is present.
