The TT simply tricks the car to think it is running in high altitude mode. Basically make it think there is less signal from less dense air. Probably still within the limits of what the car is designed to run in say, Denver, to maintain stock power production but doing it at sea level or so will make more power.

However, add heat and low altitudes, and I can tell you first hand that in the summer in AZ aka 100F or more ambient, the car pulls timing all over the place because the TT can't adjust it for even in the "heat safe mode". Intercepting a few signals, much less only 1, is just not the right way to do this.

It would be most helpful for a few of you engineers (Orb, scalbert, ...) to get together and write a short description of each tune, how they work, what variables are modified/controlled, and what the consequences/risks are.
