No one makes a 650cc fuel map for the TTZ. The guy I got the injectors through had a custom map done from Japan. JUN map the original map, which his chip is a copy of. But it required some serious tuning to get the A/F right. I had to richen it from 3000-4200 range, then lean it out big time up top after 4800... was like 8% added low when the turbos start to spool, and 11% removed at the top... Still had about a 12.0-12.5 A/F and that was at the tailpipe, not the downpipe.
