For those that live 4-6 thousand feet above sea level what kind of aftermarket boost gauges are you using in your LNF (Besides the RPD) I'm looking at getting an electrical one since that is the kind I currently have wired up on mine. Going for reliability here, mine say -9HG key on engine off -.- Haha any input is appreciated.

 

I'm not an LNF but running the Defi Racer gauge, great quality part but not cheap.

 

I was looking at those, bit pricy but I know they would work perfectly.

 

Yeah I have three of their gauges, each was more expensive than the wideband I got, so worth it though.

 

Glad to see you agree with our recommendation Andrew....

As far as your gauge reading, at 4000 ft above sea level, you should see around 25" of HG ~ 12.6 PSIA~ 87.5 KPA. As altitude increases, baro pressure decreases.

 

im running a Prosport Premium boost gauge on my car.

Its spot on accurate as I've tested it with stock boost gauge and the prosport.

My car reads 20 hg in vacuum.

im at 5800 ft above sea level.

 

I run an AEM boost gauge and it calibrates itself everytime you turn it on
