There are a couple things that I have found that can create a clunk.
Aftermarket brake pads. Some of them have a bit more tolerance in the caliper side to side, in addition to that, the caliper pin slots could be a little larger so the pad can shift more under braking. This is one of the big...
They also re-ziptied the case and everything with the extra zip ties I left inside.
A+ experience with AT.
It was a week turnaround. It probably would have been quicker if last week didn't have a Monday holiday and we didn't have a snow storm roll through that delayed it a day or two.

Amazing how most people here are just literally talk out of their assholes with zero experience to make those talking points valid. Here is an idea, if you don't have a direct or indirect experience (meaning not something you read on the internet from an equally stupid or inexperienced person)...
BM3, MHD, and MGF you can see it via the tach with steering wheel controls. Ecutek, your tuner can hijack the torque/hp gauges on the center screen to display ethanol percentage.
Reality is that you shouldn't have to check it very often so any of the above are a good solution.
