My question is this, are perf 'flashes' able to be easily detected? Dinan or Conforti? I'd assume they can hook up to your ecu and detect a flash pretty easily, or can the programing be 'hidden'

Even more easily detectable. They'll know as soon as they plug the car in when it was last reflashed.
With piggybacks, they have to look and see if wires were altered.
The only "invisible" option is the SSTT.
