Trans brake question?

Who here run a trans brake and a msd 7531? When I use my trans brake you can hear my car break up. It's like it hangs on the rev limiter a little. It will only go 1.52-3 60 fits off of it. I have rewired it and added a extra relay to see if that would help. Any one have this happen? Is it the solenoid or in the msd box?

Does the box have a 2 step built in? Is it wired to use the 2 step?
I am not sure what you mean by your description of the problem.
Do you mean after you push the TB button in or when you release it?

After it is released. The car will foot brake to 1.32-1.35 but on the trans brake it will only go 1.52-3 no matter how high I program the box. This a digital 7 programble box, I can adjust my launch rpm digitally. No matter where it is set 2500 to 4500 it goes the same 1.52-1.53. You can hear the car break up when I release the button.
