Makes one wonder about the offset variance due to temp of the injectors too. Not every injector vendor will have the same thermal effect. I'm thinking more of pintle vs rotory injectors but even the variance of one pintle design vs another would be interesting. A very hot inj vs a cold one.
Then there is the variance from inj to inj in the same batch. I know the stock injectors were way off from each other. The RC ones are rotary and matched.

Something else comes to mind, not inj related.
Some have relocated the air temperature sensor. Without tuning
for that move there maybe even more optimization that could be done.
