I put a gt3582 turbo on my car and now i'm making less boost then before.
The old turbo (k04) was making 17psi but now the most i can make is 7psi
This is where it gets weird, I installed everything and then test drove it and could only make 7psi.
Then I done a boost leak test and found 3 big leaks and I sealed them.
After I fixed the boost leaks I test drove the car again and could only make 5psi, exactly that don't make any sense,
So after that I started looking at the wastegate and the easiest was to test was to remove the wastegate and make a flange to block the hole.
So i went for another test drive and was expecting the boost to go out of control but the most I made was 5psi again.
I also checked to turbo shaft and it is ok.
At this point I am lost and not really sure what to make of this.
Does anyone have any ideas where to look next because at this point i'm sick of this car, it has been nothing but a problem child from the day I got it.
