[DC] Why is Wally West so much slower than Barry and Bart Allen?

Didn't Wally do the same experiment that Barry did? Why is it that he turned out so much slower than Barry and eventually Bart?

Wally West was "flashed" when he was a kid.  His body responded to it differently.  As he grew, if he sped past a certain point, it'd hurt him.  In addition, he had some psychological issues that occasionally prevented him from accessing his full range.
