Default boost gauge

I had my boost gauge hooked up to the waste gate vacume line but I moved it to the fpr line and it reads vac not boost. Is that normal or is there another place to hook it up.

Default RE: boost gauge

it should read vac and boost. take a picture of the line with the T fitting and post it. when properly installed, you will read vac at idle and extremely light acceleration, and boost under normal and hard acceleration. does your guage read less vac when you accelerate? is your car losing power?

check to make sure that all fitments are tight, and make sure to use zip ties or clamps on the t fitting.

6 is not right for boost, should be reading a spike around 11? for 180, more for a 225

Should spike more than 11 I think, but what the heck do I know about stock, lol... It should be holding pretty consistently around 11 from what I understand. do what i said to do...now!

one more thing, this may sound obvious, but make sure your boost guage is reading '0' when your car is off. It might also be the boost guage if the car feels fast enough.
