More than likely shift points will need to be changed to prevent it from bumping the limiter on the shifts. If you have never had any tuning done there are a lot of other things too. Can take torque management out, change shift firmness, remove shift delay from shifts, I am sure there are others too, these are what I can think of off the top of my head.

Yup. I needed a tune for my SS3800 with OEM 3.23s. Make sure you get rid of the P0751 amd P0757 codes. I still need to do that.
