I was wondering what is the difference or benefit of using a dynoflash/safc 2 instead of just a dyno flash?

 

With that combo, you get all of the special features of a flash plus the ability to fine-tune for any situation beyond your base flash settings. You can change it up for different octanes, different boost levels, different temp/humidity, or any combination of the above. It allows you to get optimum performance in all scenarios if you know what you are doing and have the proper monitoring devices...

 

I have a custom Dynoflash, and just bought an SAFC to fine tune for race gas.
