Over 40degC is not good.
Tho "technicly" you can be too cold, in practice i dont think thats possible, everyone whos seen mega cold temps on the ACT gauge all say the car was faster than ever.

You are not supposed to be charging the engine with temperatures below 0 degrees Celsius. If so, the condense in the pressure pipes of the engine will turn to ice, and ice at the air velocities experienced in a cylinder head... Well do some quick calculations...

Testing the future
with a low ACT comes dense air. denser air requires more fuel, but if it gets that fuel it produces more power. that's why a turbo car feels mch faster when it's cold.
the down side can be though, particularly if it has been mapped on a chassis dyno, that such dense air is not accounted for in the mapping, and it runs lean. that's why so many engines die when held flat out in fifth for a long time. the act drops as there is massive airflow over the intercooler at high speed.
