`12 Rxt-x strange boost issue

[leftie712]

2012 Rxt-X
I have 84 hours, everything is stock. During last ride I noticed that my boost gauge is not showing anything unless I hit it hard. Normally I would see bar or two just at cruising speed. Also its seems no difference if I am in normal or sport mode when it comes on how hard it pulls. Still seems to be fast but I could always tell difference between normal and sport mode.
I did check supercharger clutch slipping according to 3tfdeep video and it shows at 10 N.m so that looks to be within range.

So not sure what could be going on, any help would be appreciated.

Thanks guys

Check to see if you are getting water from the intercooler.

If water was getting into intercooler, wouldn't that cause oil to become milky also?
And make it run rough?

It only takes a few minutes to be sure

So just remove intercooler to see if it’s wet inside?

Or the hose from it that goes to the intake and look inside, the boost gauge runs off of the manifold pressure sensor and water could cause its failure. If its dry then consider replacing the sensor as it affects how the engine management sets the parameters, check the plugs to see the color and if any are corroded or rusty.

Thanks Digdog, everything seems to be dry, plugs look good also. I did pull map pressure sensor and it kind of looks like there might be couple tiny drops of something in dark color. Will keep it out to see if it will dry out, test and replace it if nothing will change.
