I have a quad monster monitor I purchased when I first got my truck. Anybody have any experience with this guage? It seems it is pretty inaccurate as far as I can tell. Other people have checked it and agree. I have checked it against the juice attitude and they are way off.

What readings are off?

Pyro and boost way off the attitude. The third I have monitoring the oil temp which seems high also. I guess you would say all of them.

Murray, what is your Oil Temp reading? Mine typically reads 175
to 180, and has never reached over 196, even the the South Florida heat
& humidity. Seems reasonable to me, but I have nothing to
compare it to.

Also, is your pyro from the attitude mounted similar to the Quad gauge?
This could lead to a different reading if coming from a different
location.

When I had the Predator installed (125 HP Tune), the highest boost
reading I got was about 27.5 psi (measured from a "T" in the wastegate
hose). With the Attitude, I get about 25.6 psi on level 5.

I am running synthetic and have seen as high as 228. The pyro was compared at the same rpms from the same location by switching out the sensors. I have the same T in the wastegate line and don't even come close to those boost numbers.
