05 TCM not supported

[Doc]

Im having problems with my Diablo Pred.
its telling me that my TCM and pred. are not compatible when trying to change the shift firmness

i installed the 91 tune and changed the tire size ... removed MDS changed my rev limiter but when i tried to chage the firmness it said this feature wasnt suppored by my TCM

any ideas how i can correct this
