yeah now i'm gonna check and see what my boost is actually set at. thanks again.

 

Hey everyone,

Sorry for bumping such an old thread, but my Defi Boost gauge has been sitting about half a PSI below zero for quite some time now, and I do my best to ignore it, but now and then it drives me insane. Is there anyway to zero out the gauge without a control unit??

thanks in advance.

 

^^If you don't have the control unit, then this doesn't apply to you. You need the CU to operate the gauge.

 

I see.... Is there any way to zero it out still or is the unit pretty much defective?
