Sasuke was trained for speed because his current/past speed was not sufficent enough even if he was boosted. A boost of speed is simply useless if your original speed is 2 and the speed boost is double, it would give you 4, but your opponent speed is 5, so it's still slow. So, having your speed and moves improved enough to outspeed Gaara's sand already makes the Chidori even a more perfect jutsu.

You're also forgetting about the Tunnel Vision, tunnel vision affects when the user runs with the Chidori? While it doesn't when they run at the supposed same speed or even faster? If I'm not wrong, I remember a mention about the comparrison/relation of Chidori and A's Lightning Armour, I don't if it actually exists.

And Kakashi made the Chidori while he was young, and not obviously at the speed of Lee.

As Guy had mentioned, Chidori is just a jab/thrust, it's secret lies in the "Impossible speed"

And do you know that the "Chidori" subject in this discussion is over on Sasuke using Chidori means that he can run at his full speed, which kind of disolves the whole arguement with the point that it doesn't boost speed, since that means, it just runs how the user estimates his speed on.
