jet dynamic spectrum tuner?
Looks like HP tuners or something similar.
I would do a lot of research before you tune anything yourself. Not saying that you shouldn't do it, just saying to do your homework.
That's how the tuner for my truck does it. He is the only tuner who can make changes in real time, but it wasnt cheap.
