As a result of CO sucking the mechanic through the engine a few years ago, the process is much more confined to start, run, shutdown. The TOMC send a detailed sheet of restrictions to you when a run is required.

There is a bit more to it. Most of the times I have done engine run ups, the issue being investigated by MX may not be successfully adjudicated by the pilot running up the engine.
I have had MX folks ask tons of questions about the engine run up after being performed. Not my job to troubleshoot. Their trouble-shooter guy needs to get r done. In essence, a pilot's "successful" engine run could return an AC to service that really may not be ready for prime time.
It's not simply a matter of "normal procedures" It's a matter of the safety of the operation, what's at stake, and what outcome MX is looking for you to provide.
My MX entry has read like this in the past: engine run up accomplished per MX request at idle power. I provide no other explanatory information.
If a maintainer wants to return the jet to service based on that, that' sup to him.
