This is the position of my boost guage when the engine is off.

Should it be dead on zero, does it need recalibrating?

 

Just use it as an excuse to buy a decent one

 

I only jus gt it! Liked it cause It matched the Std dials best. Prob gna sent it back tho. N the gauge is jus gt be an indication as Im gna buy the SECS unit in january.

 

So is mine out as it stands?

 

I`ve the same guage as this and it reads 0 when the motor is off i guess it will read a little low , most guages are out a little but they all give you an idea of normal readings.

 

This type of gauge is for indication only really - once the pointer moves away from the zero position with the engine stopped it's pretty much u/s. You can reset it to zero with a blunt screwdriver through the back of the gauge, but you can never rely on it being a true reading.

Sorry to hijack your thread!

I've got an HKS gauge that reads below 0 when the car is started!!! I was told that the engine bay was pressure washed before I bought it and it was at that stage it started reading wrong!

Will mine have a screw which I can adjust????

Sorry! Thanks!!!!
