Is a new tune required ?

[ESPN8]

I live in Northern Ontario Canada . Summer temps up here can ( This year ) get up to the low 100 degree temps .
If you take the Car to a Dyno shop and get it tunned at that time when its hot and humid , should / does the Car need to have a re-tune for other times in the year , like now or Spring time . The temps get to the low 50 and 40 degree mark .This past week its ben in the mid to low 40's .
For those that have not experienced this type of cold in their GT500's , it feels like the car has just gained another 100 ft lb's of Torque .
The power comes on like crazy.
So ,back to the question . Should the car be re-tune or not ?

if properly tuned it should not need any further tuning. if the temps are that much different you could certainly get some piece of mind by having a couple of pulls done to check out the a/f, boost and power levels

You should not need a new tune unless your adding new toys. But as stated doesn't hurt to have the tune checked out.
