I feel she is getting stronger, just not as strong as fast as Issei, her Extinguished Star and Ultimate-Class performance shows this. In fact, what she does with Gasper is no different than what Sairaorg is doing with Regulus, basically using an Evil Piece to increase her power using a Longinus subordinate. In fact, if she is Super Devil-Class as she was implied, she in fact made herself stronger than Sairaorg, and that's nothing to sniff at.
