I thought these cars are not modible, I guess I am wrong! I just unsodered the orange thing, I think its a cap, it says 103 on it . Anyways its the one that conects to the pink and brown wire. The wires also conect to the charging tabs. Keep in mind this is all in the car. Now my cars is faster. I don't on but the top speed is more higher. It also reacts more responsivly. I don't konw maybe it's just me cause I have'nt been running this little guy(been working on my interal dual cell shen). Okay please don't attempt this mod if you not to sure on how to unsoder. You can easily melt plastic if you keep the sodler gun on the charging contacts too long. This also voids the warranty so be careful! Sorry for the long post!
