I've got an HKS I got from a forum member that's not supposed to be a knock-off. I'll deal with the ricey sound if I'm not beating on my turbo. Please take a peek at the 10 second youtube video and let me know what you think. It sounds like its surging a bit to me. The video is my first weekend on the new build so I'm on wastegate pressure ~10psi.
Reading around for suggestions taught me that sharing the signal line is bad so I moved the BOV to its own source. Now it seems to make a more concise 'sneeze' without the extra pulse so problem solved for now beside the obnoxious ricer mating call. Every time I shift, I expect to see a horny civic in the mirror wanting to frisky.
I'm trying to go to the track on Friday and this test drive showed me my fuel has gone crazy (AFRs swinging wildly). It's too late tonight to troubleshoot but I'm glad I found this out now instead of on grid Friday morning.
