Like Mobius1 said, make sure you install the TST first, then stack the EZ.
I do not know what TST program you are using, but I found I made the most power with the standard program 5/2. With a stock CP3, any tq setting above 2 taxes the rail too early in the rpm's, and it cannot catch up later so you lose hp on top. By running either of the "twins" programs, this taxes the rail even sooner, so I would recommend setting the tq on 2 and leaving it there no matter which program unless you have a modified CP3.
TST 5/2 EZ 2 or 3 and you will be knocking on 500hp.
