DS8 also has dyslexia and dysgraphia (diagnosed at six). He made a lot of progress using a book called Toe by Toe ($40 on Amazon). It requires 20 min. a day. We did it at home together however his school was so impressed with his progress they started using it with a few students there. It helps with decoding and relies heavily on nonsense words so gifted kids can't cut corners by tapping into their large vocabularies.
He also did a six week session (4 hours a day, five days a week) with Lindamood Bell in the summer.
This combination was extremely helpful. Within about eight months he went from struggling with BOB books to reading chapter books for fun.
He still has dyslexia/dysgraphia related struggles but reading isn't one of them.
