After many searches on the web and reading on the forum I am doubtful about the galletto v53, price interesting and different accessories. But I don't understand some things: I can use it to operate in the bdm? How it works in the serial? For the ecu Marelli pu? be good? or spending a little more? c'? better for use, solely to work on my point, that I have to do? Sorry for the many questions but neophyte that I am a bit lost in this kind of choice
