I have a blitz sbc-id boost controller...When I turn the boost controller on, I can hear a tapping sounds when the turbo kicks in. When I shut the boost controller off, it goes away. Anyone have any idea why that tapping sounds is there? I didn't have that problem before. Any suggestion why anyone? Thanks......

I would assume knock or ping since you said when you turn the boost pressure up. The PCM is prolly tryin to compensate for the higher pressures, however it is causing a knock. Anyone else think thats it?

I think you have rod knock....




Just kidding, it is the SBC-ID control solenoid. They all make that noise, it is annoying but turn up the radio or open the window and you wont hear it.
