I want to install a trd supercharger in my xr, but there is no toyota dealership where I live (S. Korea). And mine is currently the only xr in Korea, so mechanics do not know much about the engine. Since there are ECU reflash tools (but not Toyota) here, does the supercharger come with the data needed for the ECU reflash? If not, where would i be able to get the needed info? One more thing. How much faster will my car accelerate if I install the supercharger to my XR? Be waiting for your reply. Thanks..
