just installed my boost guage last week. Today I drove it up to 200kph in 5th gear. Checked out my boost gauge & pressed the recall button & was reading only .7 bar. i done some few acceleration runs in 2nd & 3rd up to about 6k RPM & still reading .7 bar. Do i have a leak? if so, where are the places I can check? The car feels really strong.....no signs of sluggishness.
would it have something to do w/ the blowoff valve? everything looks ok.

 

pare ko... where did you tap the line for the boost gauge?

 

same place where it was on the "HOW TO" defi boost guage install.

 

Why'd did you go so fast just to test the boost gauge? 200kph is like 140 isnt it?

 

180kph is about 110 mph, so 200 kph is only about 115 - 120 mph...

So where did DEFI say to install the TEE tap???


EDIT:

Okay, found install guide, did you tap it from the vacuum line that goes to the fuel pump? If that didn't work for you, try the vacuum line between the throttle body and the Diverter valve (BOV)...

 

Off the vacume source on the back of the manifold.

 

Oh ok, I thought it was a bit higher than that...

 

I followed exactly the DEFI boost gauge install....The vacuum line that came w/ the boost gauge looks kinda small thou compared to the defi one.
