Wanted to see what I could get for some advice on this issue. Earlier today I been driving and fully opened my 09 wrx and when I got around 6k Rpms I noticed a loud pop sound kinda like a backfire around my turbo area. And noticed my CEL came on. So I went through my Cobb AP to check the code and got the PO224 code. I erased the code and reset my ECU. I haven't gotten the code again. But I have been to worried to open it up I just drove normally the rest of my drive. I have noticed my boost gauge reads almost to 22 pounds at full boost. And the Cobb stage 2 map I'm on tells me it's suppose to be at 18psi at peak. Anyway well just hoping that someone can come across this and see what they think or give some advice to me. Thanks
