Normal and Track Key

[Tyler72]

Alright, as promised, here are the Dyno graphs.

As you can see, they lay over each other perfectly. The only arguable difference is between 5500 and 6800, with the track key making 2-3 more HP and 2-3 more Lb/Ft torque.

The biggest differences I can feel ON TRACK with TK are not at WOT; I have similar dyno experience that the WOT curve is almost/exactly the same as the silver key. The TK makes a highly noticeable difference in part throttle response as well as engine braking; both of these are very helpful on track.

Also OP if you didn't buy the software package yet you can get it for $220 at Tousley: Tousley Ford Parts Depot
