I have a tune and my rear end was replaced under warranty.
I have a tune, headers, intake, tb, HF cats, and my rear end clunking noise could not be fixed by changing the fluid/friction modifier.
When the dealer decided they wanted to open up the rear end, they had to send the file to GM containing a snapshot or w/e of ecu. GM gave them the go ahead, even with my tune, and they replaced the ENTIRE rear end. Total would have been $1,750 and I got a new rear end with the rest of the car at 25k miles.
So dont give up hope if you think your mods or tune actually didnt cause the damage.
