Hey guys i just installed the Podi boost gauge and i gotta say, it looks awesome, but i feel like i messed up or something just isnt working properly.

When the car is off the gauge sits at -5 below zero, i dont know if its suppose to sit here but i always thought the needle would sweep all the way down to -30 when off, but it does read the boost of the car getting 15 psi and -20 at idle, im APR stage 1 right now, so those sound right to me.

I bought the mechanical boost gauge package if that helps any?

Thanks

Is there an adjustment screw for the zero position? With no power to the guage I would expect a mechanical to be at 0 and an electrical to be the lowest reading. Your readings when running look to be about right.

Hmm true, ill check and see about that adjustment screw, as of now everytime i shut the car off it stops at -5 and its a little annoying lol . thanks for help!

MapleSyrup

no i couldnt find an adjustment screw anywhere. any other suggestions?

The guage is not mechanical.

I have a podi dash mount gauge also, 15psi petal to the metal, and -20 at idle sounds correct.
remember the guage is a simple pressure gauge so if your not generating any out flow exhaust then your car is sucking in air, hence the -20
-5 when the car is off also seems right to me, i double check and get back if i am wrong.

Ok , it will shoot to 16-18 psi when its pedal to the medal so to say, and -20 at idle, the -5 is when the car is off and the needle is resting, i just thought it was weird that it was sitting at -5 when there is no vacuuming happening, just a little annoying, but i learned to live with it lol.
