Visited my dealer today as I had read before that we were going to be getting a code like valet mode to improve vehicle security. I asked them and they said it is out for the 21s currently and they have done a few, and they are in the process or rolling it back into the prior year vehicles. What he knows is that like the valet code you will be able to enter a code limiting the horsepower, he said 23hp, I ready somewhere like 3hp, regardless though he said that once it is done you can't program any new keys, so he said when I did it he recommended getting another key or two or if I only had 1 to at least get a 2nd. Figure some of you might want to know especially if you have a 21 now. Sadly, I will have to wait for the 20s, 19s, before it gets to my 18 evidently having an opportunity to get it.
