Talked to the tech, and he'd said some engines could need a lot of miles before the ECU treats it as fully "broken in".

So his recommendation was, interestingly enough, not to worry about power or anything, but just put miles on it till the ECU stops providing the safety buffer.

The computers on these cars are a lot more complex than we often give them credit for.
AFAIK, there is NO break-in period in the ECU... I've never seen any evidence of it in any thing I've ever come across... Got my Camaro on a Wednesday and was at the track on Sunday... car pulled hard all the way to the redline...

The next week put the car on the dyno...
