Ok that's just retarded. Start the car and let the RPMS settle at around 600 and then drive off, this takes about a minute or 2 depending on temp. Then just let the car shift at around 3-4k RPMs for the first few miles. After that you can start to play around.
Idling your engine for 10min is just freaking stupid and bad for the car. Redlining after driving for like 2min is also a bad idea.
