 (1) Resistor in the IAT sensor
 (2) Relocated IAT sensor (installed in the intake stream instead of the hot

 (3) Cooler T'Stat (180 degree)
 (4) or a combination thereof
 
 Also, are you running with the A/C or Defroster? When it kicks on, there's
 a noticeable loss of power.

Also, since it warmer outside your under hood temps are warmer. Colder air
is denser and allows for better combustion since a higher percentage of O2 is
there. This complements the richer mix in open loop, and gives you more
power.
