The reason I ask, the last time I went to service, I had a rattle near the yoke and the tech asked me to go on a test drive. We went on a highway and just before he asked if I knew the car has another 250 to 300 HP. I said no. Car was already in service mode. Whole screen red, me in passenger seat. He pressed a couple of buttons fast, didn't see what he did. Anyways we get on the on ramp and asked if I cared if he floored it. I said heck no, nail it. Geez, it felt like a bat outta hell. So our cars are speed limited for sure. I asked why I couldn't buy that upgrade. He said he didn't know if they will ever offer it. So for the last few months I have been wondering what he did.
