2003 wrx wagon needs help
Aloha
I'm new to the subaru world so please bare with me. I own a 2003 wrx wagon with a few issues. I bought it about six months ago and absolutely fell in love with driving it. She came completely stock except for a junk JDM Td05h 16g turbo. When I had purchased the car it ran good and didn't seem to have any issues but was throwing misfire codes in all 4 cylinders and 02 sensor codes Since i purchased the car i have Installed a turbo back exhaust, K&N intake, STi Injectors, STi tmic, walbro fuel pump, new coil packs, new fuel Filter, new spark plugs, new air filter, new o2 sensor, COBB ap. I have done a compression check too and everything looks good. I'm almost positive the vacuum lines that control the boost levels aren't installed properly. I'm looking for someone that could possibly take a peek at my car and or teach me a few things about it Like I said the car runs good but I know it could run better. I'm new to this, but I love wrenching and I love fixing/modding my own stuff. Please help. thank you!

People don't reply very often on this forum idk why. There's only a few lines that control boost levels and you can trace them from your boost controller that's attached to the bay near your passenger side strut. Check all the line attached to the BC as well as the line attached to your wastegate actuator, and once all is checked it wouldn't hurt to run a boost leak test.

man people dont check this s+++..
i dont know wat you came to conclusions with but i have also gone to the bigger fuel pump, and am having a similar issue, ive come to terms with the next thing ill do is at 550cc injectors or slightly bigger, maybe a fuel pressure regulator also.
