Does raising idle rpm with a tuner make car faster?

I have a Dodge Challenger RT with a stock idle of 750 rpm. I used a diablo tuner to raise it to 1,200 rpm. It made the car more difficult to stop in stop and go traffic, so I lowered it back to stock idle rpm.
Does raising idle rpm make the car faster from a stop or was it all psychological?
