Take the car for a drive/thrash, then let it do its 1min turbo time down.
Come back to the car in 2-3mins and turn the key ON.
Look at the temp guage.
If the 1GGTE is anything like the 7MGTE it will be 1-3 bars higher than normal.
Sorry for clogging the thread up MonkeyPunch, just trying to clear up a few things.
