I don't see anything bs about it, its just like the ppc tuner but for half price. Plus it can change shift points on the auto tranny which no one can do right now for the solstice, and to some this is a big plus. Im not too sure about the hp increase, i bet they can squeeze a lot more out of it since you can update the software in the box.
While i agree hptuners can do more, but give the average person a laptop with hptuners and they'll say no thank you, gimme a hand held tuner and i'll push this button and that button to get my hp fix.
