I am going to be in need a SC for my 2003 Ram 5.7. I am getting some work done on it (rear is getting a 456 lsd), and I would like to adjust my speedo for the 20 I will be getting, and tune what ever I can tune.

I will be going to 05 PCM swap, but I am not sure if the State you all that since I have emissions. So right now I am just band-aiding thing until I get the money for proper repairs.

For starters I am doing the rear, and then I will be doing the trans; lastly will be PCM/engine.

How hard are the 545 to rebuild/take out the works. Also has anyone dealt with this trans place?
