the z32 kit was put together. If someone doesn't want to go to a MAP sensor, then there really is no point to the AEM EMS IMHO. (Hows that for some acronyms). If he wants to keep MAF meter, then I would think the Zem would be a better deal, economically speaking.
Also, you can get better driveability out of a MAF meter than a MAP sensor on a turbocharged car. I am ordering my Zem soon since I daily drive my car and I don't want to go to MAP yet.
