As Dom says, it may already have Stage 2 or more software already on it. But it may have been switched back to standard with a switch. Hence it doesn't feel mapped. But you would need to find out which map is on it before switching it back on without the supporting hardware (TBE, Fuel Pump etc)..
First thing would be to try a Revo Select switch and see if it has Revo software, if so then ask them what Stage?
Where are you based pal?
