Perhaps, but I personally wouldn't want to jump through all the extra hoops to prove that your modification was not the cause of the issue. Any chance you think the chirp could be from the couplers/flanges in the OFH from the engine moving under load?

Seems this person had a similar issue, but no follow up.

Not me. I was just trying to be helpful.

It's in the clutch master cylinder. Some blame it on the delay valve. In my case the return spring occasionally rattles at about 4200-ish RPM (IIRC, been a while) when it's really hot and only with my foot off of the pedal.

I get tip-in knock when I stab at the throttle from fuel cut. (engine braking) I've learned to ease into it to avoid it. Totally stock.

My car had the same issue! Took it to Toyota and the warranty covered the fix and they told me with was the "high pressure fuel pump". No more chirp for me, I hope that helps a bit

Good luck telling that to any stealership. I don't know about your tune, but with ECUTek and flashing stock, the dealer can tell a ROM was loaded outside of Toyota/Sub.

The #1 rule of dealers, if you modded it, it's the mods that caused the issues and you as a client need to prove it's not.
