Hi

I just installed boost gauge on my evo x. It seems around 10psi.

So does anyone know average boost psi of stock evo x??

I am worry about my boost is properly working.

 

For the 8 and 9 stock boost was around 18 or 19psi. Not sure about the 10's though..

 

DAMN 10PSI!!!??? turn it down, thats way too much!


lmfao!


(i think you either hooked up the gauge wrong or your car is jacked)

 

what type of boost gauge are you using?

 

I have prosport Electronic boost gauge. I changed boost tube location from T to boost sensor. And I tried to test my gauge it hits 13-14 around. I think tube was not well installed.
But I think the average boost PSI should be 16-18. Am I right??

 

20ish.

The boost should be around 18-20 psi. Make sure you put it on a line that has constant vacuum, After the trottle body on the intake manifold

 

Thank you very much for your reply. I checked my boost today. It hit only around 14 and down to 11. I still dont know what problem is. It is completely stock ecu and I did not mod WGA either. I checked my vacuum line it seems great. But there is boost filter which prosport provided btw T-adaptor and boost sensor.
I think this filter causes my boost lever down. can I get rid of it??
