I've been mulling this over, and I'm curious as to other thoughts..

I live in Canada where there is a wide range of temperatures... Although I won't be driving my car in the winter, there can still be quite a difference in temperature.. (25* C or 77* F if my math is right...)

That being said, what/when should you get a tune done? Should you tune at a time of year where the temperature is at a median rate? (eg. 12-13*C ?)

I know a lot of you guys are down in the southern states and don't have to worry about it, but I'm interested to hear what you guys (especially tuners) think on this..?

Thanks.
