Noise under hard acceleration

[Brad208]

Hey all,

I have a noise when I accelerate hard. Sounds kinda like gear rollover when you're idling through a parking lot with the zf5, but it happens when I'm making a lot of boost. Here's the link to the YouTube video I made today. You can especially hear it right at the end of the last pull, the kind of surging noise.

Not sure what if any mods you have on your rig but I have had the same thing happening to me when after I upgraded my injectors and got a ts chip to run them. I've only noticed it when i run my chip on slot 5 and 6. Tranny has just under 200k on it and my dad had the clutch replaced in 01'. A gent at my local inspection station said he thought the stock clutch might be slipping under the increased hp. Not sure what to think tho. Would love to hear a explanation from someone that may actually know what they're talking about tho.

Yall should do a run and video your gauges. If a clutch Is slipping it should show up on the rpm gauge.
