i've checked the car up and down trying to find a leak hole lose clamp and cant find anything i guess next is a boost leak tester maybe? where can i find one and does anyone have ideas where i can look for my problem?

1st gear only maxes at 15 psi
2nd and 3rd hit 18ish and drops to 15-16 right after it peaks
4th stays close to holding boost at 19 but looks like maybe its hitting 18
5th holds 19 from what i can see while driving
im running stock boost no boost controller. jus a fuel pump, intake, tbe and tune

car only has 10k miles on it any ideas? i really appreciate any help

 

try a different wastegate actuator. i had a similar prob on my WRX it worked for me.

 

is it an intake pipe or a filter? within the tune were the boost tables altered at all?

 

I would try to bypass your stock boost control solenoid with a MBC and see if you can boost more. Or else it could be an exhaust leak? So many possibilities.

 

how many threads do you need?
