Man, this is becoming way more complicated than it needs to be.
You hit the button twice. You are in PTM. You change the mode depending on what you want. Even though both lights are illuminated, you have differing degrees of traction control and stabilitrak depending on which mode you choose (PTM 5 has the lowest of all, outside of "mode 6" which turns all nannies off completely). If you hit the button again, you turn off PTM and go back to tour or sport normal mode, which only changes the steering feel and nothing else.
You get differing degree's of HP delivered, with the lowest allotment at PTM 1, and the most at PTM 5. PTM 5 gives you full Engine HP/torque from what I have experienced. I.e. It doesn't cut timing/fuel, doesn't bog you down in turns the pcm feels has too many G's etc. The whole point of the early PTM's is to help you learn the car at a measured and predictable pace. I drive in PTM 5 regardless of street or track now, because I'm 100% comfortable with the car.
