I dint get limp mode, car still felt smooth as anything just no boost lol, felt weird. what i did was unplug the n75 and it shud run normal still but there will be no boost, then this was exactly the same to what it was doin when it shudent off been, so i narrowed it down to n75 got a new one and never had the
problem since
worth a try tho mate to unplug it and see what happens.
