It didn't make sense to me as well until I thought and watched it over. Being that Impulse is Barry's grandson that means he automatically has his speedster abilities due to the chemical reaction that gave Barry his speed is part of his genetics or whatever you want to call it. The difference is that the chemica reaction that Wally had didn't have the same reaction in the sense that it put in the hospital and took awile to develop meaning it worked but it didn't have the same effect as it did on Barry. Hence why he is slower and can't vibrate through solid objects and so on.

This is why I'm saying the only way for Wally to evolve and become the fastest speedster is for Barry to die this time and not be saved so Wally can take up the mantle and reach his full potential. I have a feeling since Nightwing and Miss Martian are well on their way to surpassing their mentors that Wally and the others will do so by the end of this season as well. Come on people you cannot tell me that they are going to basically embarass one of the main characters like this and not have an ulterior motive behind it. It wouldn't make any sense especially with the amazing writers on this show. Wally is becoming The Flash before this season...bet I penned it.
