Yes my car is remapped but i doubt if its because of that. The only thing i can say is that it does not happen always so if its the remap then it should happen always. Secondly I dont remember if this had occurred earlier as well since its just been too long to remember. Anyway i can find out what the problem is. I dont fell the drop in power for more than a few secs and that too not always. Apart from that there is really nothing much I can say. Any help is deeply appreciated.
