A spec1 remap is a remap and is only as good as the hardware on the car, 9 out for 10 AGUs that come to us have harward issues, leaking pipes, weak actuators, dodge pot mafs ect... which we can sort out during the mapping session
During the r-tech remap session you will have your car tested on the rolling road and have everything checked... fue,l timing, boost and actuators ect. During the mapping session we can adjust the map to match the cars hardware and we can set the actuators to gain the very best performance.
Its the extra 1.5hrs we spend on customer cars which makes the biggest difference, the rolling road is used as a "tool" not just for fancy power graphs...
