The email tune is just as good typically if a good tuner is used.
There are only several benefits to the in person tune and the fuel pump failing example above is not one of them.
1. If on a Dyno you can optimize power production as well as provide a safe and smooth tune.
2. You can hear knock during the run and abort if needed or if the car goes severely lean. However a good tuner would never be so off to cause severe knock or a severe lean condition.
3. The ability to street verify the tune to tune transient response. Once again, most tuners have these parameters dialed in on a base file.
Note about item 2. The owner take some responsibility in knowing his car and having proper functionality of critical components. If you are remote data logging you should be able to hear knock. And if a wideband is used monitor the lambda of the car during data logging.
Many years ago I was given a bad base tune on an Edelbrock Eforce on an LS3, that I was going to fine tune. It knocked severely. The timing was way too high. I could hear it and feel the car was flat. That was a bad base file.
In my opinion the very best email tuner is JRE. He is amazing at email tuning. The key to his success is a great base file library, and applies value files based on the mods. He's good enough that with basic mods he can tune the MAF without need of a wideband. Very impressive.
