Any ECU flash tune can be flashed in and out. It's as simple as flashing different firmware to your PC. The dealer won't know however I suspect that Toyota or Subaru could tell if they actually wanted to dig deep enough (Think catastrophic engine failure). Emissions testing is not a concern. All they look for are active and pending DTCs. Unichip leaves no "footprint" even for the manufacturer's but removing all traces of it for dealer visits would be a PITA and it doesn't do much anyway.
