Yeah stick turbo. I'm at a stage 2 tune. All I have os a downpipe. I understand that boost creep is a mechanical issue, but to my understanding its because of the flow coming out of the wastegate dumping into the. DP. With the way the HKS is designed it causes some kind of disturbance with the flow causing the wastegate to briefly stay stuck open which then causing boost creep. That's to my understanding that is.
