hey guys, i just installed my Defi boost gauge. when the car is off, the needle doesnt sit completely on zero. the needle sits on the lower half of the zero hashmark... at full boost it hits the hashmark right before 20 (im assuming thats 19)... and at idle the vacuum reads exactly at 20 mm HG, are these numbers consistent with what you are getting on your guages? or is mine off a little bit.. .i m mainly concerned cuz when i turn the car off the needle is just touching the lower part of the zero hasmark, not completely covering it... thanks in advance.

that sounds like the needle is a little off. return the gauge and get a new one, if you want it to read dead on. or just keep it, it will still work just fine

hmm so it is off.. well i just got it like a week ago, but my wife threw out the box...!

 

is it the d gauge?

 

yea defi d mechanical boost gauge

 

EDIT: Too slow

 

???

 

well my gauge is a little off 2, depends on how you look at it

 

thats how mine looks, well actually i havent looked at it from that angle, what ill do is snap a pic of it after work tomorrow and post it up and u guys can tell me if its off or if im just being a ***** about it...

 

you posted what type of gauge you had before I asked

 

i have the same gauge, mine sits below zero too. i have heard that happens to a lot of people.

 

Des it give inaccurate readings because of its position?

 

max boost is at 21. which is regular on the 05's

 

even though it sits just a hair below zero, max boost (i have a '03) hits the hashmark right before 20. so im assuming thats 19 which would be accurate, but those smaller hashmarks dont seem to be 1 psi each (between 10 and 20 psi.)
