I'd definitelly go with someone with expreience since i wouldn't want to deal with soldering it, although I've put chips into Playstations before. I'm dealing with my car here. It's not hard, but I wouldn't want to mess it up.
Sorry no pics. It took about 1/2 an hour to install. you have to take the carpet out of the passenger side floor (by the glovebox) and follow directions. It seemed easy enough, but I wouldn't do this by myself without first seeing it. There's just something about electronics that when I don't know too much abouta certain part, it scares me to play around with it. Computers are another story.
I would nonetheless recommend this to anyone looking for a few extra ponies and would like to see their car run smoother. I'll have to keep you posted on the developments, though.
