So I've recently posted about this issue before, but it originally wasn't a boost leak, it was an exhaust leak (pre turbo). So now that I have better gaskets that issue went away. Now my problem is still not being able to reach target boost.
My car has 134k miles on it. I am currently on a Stage 2 OTS map, 100% catless (3 inch turbo back w/ bellmouth DP & Up Pipe w/ flex) and running the Cobb Short Ram SF intake. My car is only reaching high 13 psi at best. A WRX comes from factory @ 13.5 psi and this stage 2 map is rated @ 16.5 psi target boost (I believe). The car idles around 700 rpms when all warmed up. So I'm curious what I can check or what is most commonly the problem.
Let me know if you need any more info! Thanks in advance!
& yes I'm aware of the Boost leak tester kits you can make / buy. I just wanna check the simple things real quick before going out and buying the stuff for the boost leak test.
