Standard procedure is to drive the car below 4K and off boost until temp hits the first white mark. Don't know how mandatory that is but seems reasonable.
Several items contribute to raising the idle when the engine is cold. Most influence is from the Aux Air Regulator. Secondary is the Aux Air Valve (if present) and then the Thermol Time Switch which kicks the timing up.
