I have (still partialy installed on my car) a Greddy E-01 EBC for sale for $300. Currently only being used as a digital boost guage, but everything else to make it conrol boost is there, and works (sensor, controller, screen, brain, remote, and memory chip). Im selling because I dont realy need it, and I think its meant more for bigger turbo cars, as it has gain controlls and gear/rpm specific boost, its a little complicated for what I need. I'll leave it installed for now so you can confirm it works. Might consider trading for something equal value, throw me an offer. Please send a PM if youre interested, located in Clearwater.
