You package should have come with some software and a USb cable to connect to the trans controller. You should be able to tune it there. In addition, there are a couple of switches you can connect that will put the trans in performance mode, the wires are there, you supply the switches.
The directions and paper work leave a lot to be desired as far as what to connect to what. They mix pin outs and connection information all into one page. Its there, you just have to dig it out...
