Car won't go past 10psi, WTF?

[MadrussianSVT]

So I finally put my car together after changing clutch and now it won't go past 10psi. It's like it's building boost fine till 10psi and than it feels like I got a two step that hits the limiter. car was sitting without a battery for a month, also I removed the rest of the exhaust living just open down pipe and second u2 sensor zip tied to undercarriage. Mods on the car: Apexi boost controller, Apexi afc, 650cc, 250 walboro pump, 57trim turbonetics. What can it be?

99.9% Chance. Boost Leak. Do what simple jake says. Or maybe play around with the Boost controller.. What is it set at?

I checked both Apexi units and they indicate same numbers and settings as previously so I don't think it's a boost controller.

Oh snap! I think I found the leak, one of the clamps were sitting to close to the edge on silicone coupler and sled off. Problem fixed!

Gotta hate those leaks...

Finally! Someone that admitted it was a boost leak!

 

[MadrussianSVT]

Although I did have a loose clamp, it wasn't the cause. I connected one of the vacuum lines to the wrong fitting on my blow of valve, swapped it and what do you know, full 21psi now!

Probably a boost leak, you can buy a boost leak tester online or make one.

I swear if you typed "10 psi" over 3,095,543,547 threads would pop up, all saying the exact same thing.

Did you not read a single post before replying? Not even the one by the OP that described what the problem ended up being...DIRECTLY BEFORE YOURS?

It's cool man, I'm a noob when it comes to DSMs. I honestly don't have time to do extensive research on the issue, figured some of you guys might know a solution.
