Yup
Because we can...
I wanted mine to read Inches Hg ABSOLUTE
The factory gave me PSIG and InHg Vaccume....

 

Digging this up because I found the solution without buying a dimmer. Just wire in a resistance of 4.2k to get approximately the correct lighting with the Sport Comp II gauges.

 

hi guys i just signed up today with a quick question i have a 06 cobalt ss 2.0 supercharged that just last night when i hit boost the gauge stuck around 5 psi and it will not come back down is there any way to fix this or do i have to buy a new gauge? any help on this would be appreciated thanks

 

Sounds like your gauge came unplugged or you popped a fuse. You can try pulling the A-pillar cover off and make sure everything is plugged in.

 

you can dim the gauge if you wire into the dimmer wire forgot which one
because the four wires are power ,ground ,dimmer ,and boost signal

 

where exactly is the fuse located at? it works when i hit full boost but it will not come down any further than 5 psi
