I just installed a Gimmick turbo inlet pipe on my 06 STi after finding my stock one was torn wide open. As soon as I got the install finished I took it out to see how it ran. The car ran fine with no CELs, but I was hitting around 23-25psi under hard acceleration. Another thing I noticed was a much more pronounced wastegate fluttering noise. The Car has a Cobb Stage 2 kit, Cobb SF intake, afta maf pipe, and box. I was running the 91octane Stage2 Cobb OTS map at the time. I haven't gone out to data log yet. Do I just need a Dyno tune to fix the issue, or did I jack up the install?
