Whether you can feel the difference is another matter.
I am tuned and do not allow them to plug in my vehicle. I had the CS EDC settings coded in, partially to avoid doing a full update and having to get a new file from VF Engineering (out of laziness and the need to wait for them to send me a new file and ODBII cable).

I get the car back either tonight of tomorrow, let's see how it feels.
