Whats up guys, I recently got rid of my crap factory gauges that came in my 9. I installed a Defi racer gauge, only for it to give me the headache of a lifetime. The gauge itself is getting power, as it lights up and does its opening ceremony, however, It will not read vacuum/boost. I used the stock line that was connected to my factory gauge, which is providing vacuum ( I can feel it with my finger ). I searched and cannot come up with a definite answer,as I find is info on the BF series gauges. Excuse my noobness, any help is appreciated. Thanks.

 

With the BF gauges, they recommend using the FPR hose for boost/ vacuum. I would Tee off that and try IF the racer version recommends the same.
