I was over reading about the jmod over at tccoa and some other mustang sites, It mentions changing accumulators on certain models and drilling some holes bigger on some years and not on others.

Is there a write up anywhere specific to the 99 plus? There was also some mentioning that the holes need to be a little bigger on higher hp cars?

I'm a newb when it comes to auto trannys and would appreciate the help,

thanks.
