Hey guys - finally got my Defi Guages installed last weekend but the boost guage just sits there and twitches.

It goest through the entire 'opening ceremony' without a glitch so I at least no the electronics are wired properly...but when I start the car and drive it around (definately in boost) the guage just sits at zero and twitches...

Any suggestions on what I did wrong?
I'm going to check the T connection where I hooked up the vacume hose...looking at the directions on MKIV.com it is pretty ambiguous as to where it should be hooked up...so I'm guessing I made a mistake here.

Anybody have a photo of where they added their T connection?

Ekow,

It should pull off any vacuum line on the intake. Now, I wonder if you have a vacuum leak that is causing this. You can boost check it to verify and you can switch to a mechancial guage to see if its the sending unit.

Maybe your boost sensor is no good? Or maybe you arent getting a constant vacuum source where you hooked up your vac hose from the boost sensor?

Checked the hoses - they were wrong....and I fixed them.
Can someone explain to me what level of boost would be normal?
I hit 1 Bar during my test cruise
