High temps and thin air can often lead to overheating, especially at WOT. 
Nonetheless, there are some thing you should check to be sure your cooling
system is functioning optimally.

1) Make sure the louvers are wide open (mine were not).
2) Check that the fans are functioning properly (mine were not).
3) Do not run without the belly pan (at speed, it does help in cooling).
4) Clean out all debris from the radiator and AC condenser.
5) Use clean water with a low concentration of anti-freeze.
6) Add a bottle of "Water Wetter".
7) Make sure the coolant system holds pressure.  (Fix all leaks.)
8) Although it should not be necessary, a DEVEK radiator may help.

In my case, the final output stage (FOS) was causing both the fans and the
louvers to malfunction.  The "new" FOS has cured my overheating problems. 
YMMV.
