Alright i'm a new guy to the Nissan platform. I'm looking to get an RB25DET 240sx. There is one close to where I live. The guy said he has a ROM tune + SAFC. I thought this was a one or the other type deal. I know subaru's used a tunable access port off of Cobb but I am unfamiliar with Nissan? Also I read that the SAFC tricks the ECU and doesn't actually reprogram it.

So basically...

-can you have both?
-Are there any cons to this?
-Are there any pros to this?
-Is the SAFC bad for the engine?
