No, there is no specific map by Mtune when installing the intercooler !
And yes, I installed the intercooler this summer, with higher outdoor temperatures (more than 30?C), engine seemed more responsive, and more intense push to the top of tower account (high motor rotation).
In winter with cooler temperatures, I'm not sure that the intercooler brings a palpable gain !
Although mechanically, this item is very good for the turbo fiability/reliability !
