I used to get about 5-6 psi off the WG spring, now I only see 3-4. If I set the Greddy Spec II to 7psi I get 6psi.

So could it still be a boost leak if the boost controller gets me the correct boost level according to what I set it at???

I thought the green spring was like 9ish???

Are the springs interchangable between WG sizes???

 

Sounds like a boost leak.

 

Thanks for the reply, I figured just as well. Just ordered a bunch of T-bolts from Stan, so hopefully that will fix it.

It's just the boost controler thing has me confused, if I set it to 7psi, and it was a boost leak I would think that I would only still be seeing 5-6psi.

I'll figure it out, I always do

 

how are you able to set it to a psi value? mine only displays duty cycle

 

def a boost leak.. i had the same problem except i was only getting 1psi. first i used a bike pump to locate the leak but the leak was so big i had to use a air compressor to find it. it was leaking through my stupid EGR which i plugged up after i found it.
