My DS's therapist has been using "Unstuck and on Target" to work with him on mental flexibility and it seems to be helping. DS is also on Clonidine (in addition to a stimulant), which certainly doesn't hurt.
My DS (now 11) sounds very similar to OP's DS. Through his IEP, he's got counseling hours with the school psychologist who is wonderful (we are so lucky to have had her the last 3 years). She and the special ed teacher have worked with this program and another called SuperFlex. The both recognize this type of 'inflexibility' and rigidity. DS has made a lot of progress because they are able to work with him in the environments these blowups happen.
FWIW, DS is on Concerta 18mg. My oldest takes Intuniv. It's really helped with dysregulation exacerbated by teenage hormones.
