the heat light is your knock sensor mate, the best thing is to go and take the car to get mapped because the last thing you want to do is run lean esspecially on boost as this can cause you to throw a tip.

The heat light could also be your injector duty cycle is too high, which is likely as you said its running lean at the top of the rev range. If the heat light flashes quick then its knock if slow flashes then its injector duty.
You really need it mapped correctly and if you are trying to map it yourself or live map it then again i would advise taking it to an established tuner near to you.
You could always take a road trip (with a trailer or seriously off boost) over to the uk for one of our tuners to map it for you, I know a few mrc members have taken the journey to germany a few times not least for a ring trip.
