I never said that a rolling road remap is better then what we offer because personally i really don't think it is. Alot of people prefer real time driving remaps because that's exactly what they are, real time. It also means it's easier to get the map exactly how you want it at the time. In my opinion a rolling road remap would be better for you going off your concerns that you spoke about but be aware that the car will still need to be tested on the open road once the remap has been done and then maybe tweeked a few times after that to get it how you want it.
In respect to how we remap the cars, we have many different ways and techniques of doing it all depending on what the car is, the mods on the car and how the owner wants the remap. If you wanted a generic remap then we could do that without you having to even drive the car. If you wanted a totally custom remap where we start from scratch then that is also available aswell.
As for the rolling road remap, no doubt a google search would bring up the nearest dealer to yourself.
