Boost oscillation
I'm sure this has been covered but most of the solutions I've found weren't applicable to my situation. So I've owned my 2002 wrx wagon for six or so months now. In the last 4 months it has been getting boost oscillations in 3rd-5th gear at anything over 3500 rpms. And has gotten worse in the last month or so. Here's a list of mods
• STI VF39 turbo • STI blue injectors • New intake manifold gaskets • STI intercooler • New hoses throughout (silicone) • Newer 04 wrx transmission • Grimspeed headers • Grimspeed y-pipe • STI up pipe • Hks downpipe • Apexi cat back • New intake manifold gasket • Gfb respons hybrid bov • Cobb 3 port EBCS • Aeromotive 340lph • Heat wrapped SPT intake I've smoke tested and sealed a couple leaks and inspected vac lines. I have a hunch it might be a boost leak but can't find anything obvious. Any help would be greatly appreciated as I've tried a ton of things to no avail |
