Getting Tuned During Winter Months

exactly. an intelligent tuner will leave room for variances which will allow the tune to be safe no matter the weather, from 10* to 110*. the base map of a tune should NEVER need to be changed and the “realtime” timing multiplication maps should leave enough room that the car is able to be driven no matter what. if your tune is so aggressive that your shit blows up due to a temperature spike (or drop) then you had a shitty tune.
