Hey, im lookin in the market for a racing ECU and i was wondering if this is real,
http://cgi.ebay.com/ebaymotors/ws/eB...category=33597. I have a 5 GS-R, will that really increase fuel economy, if its fake, where can i find the real ones.
also, how hard is it to do a conversion on my car, for a JDM ITR front end? Thanks
