When a typo shows up in the first sentence of their description. I think Ill stick with one of the tuners that many have used that didn't send a piston thru the oil pan. It is cheap... also another red flag.
Not going to say do what I did and go LMS, but... please research the options that have tons of feedback on this site before buying that thing.
I wouldn't. It looks like it is just something that messes with the signals coming from engine sensors, in effect 'tricking' the ECU to do things like up the boost or fueling.
Not something I would screw with on a TGDI engine. Either do a proper tune or don't mess with it.
