No, Impulse really IS faster.

See Wally tried to replicate Barry's accident with his high school chemistry set. Wasn't a perfect recreation. All he can do is run fast. As it is shown in Bloodlines, Wally can NOT stop on a dime like Flash and Impulse. He also doesn't have quick reflexes or accelerated senses (no helium-speak or Allen-vision for him).
