I am thinking about getting one for my Z because i have a guy that is selling me one and i had it testing and everything. Do you guys know of this brand, and is it as good as the jim wolf ecu??? I hooked up the computer to it on another z and it ran a little bit richer than the jim wolf does. It is made specifically for the low year 300zx twin turbos. Please give me some insight. It seems to work out great.
