Lexus is Toyota's premium sub-brand. D-4D is Toyota's badge for its turbo diesels. The Toyota Hilux is the world's best-selling pickup and a high-volume tuning subject. DPF/SCR with AdBlue is standard on Euro-6 Toyota diesels.
The GR models (Yaris GR, Supra) have a growing tuning culture. Toyota has an active JDM tuning community (GR Supra, GR Yaris, GR86). The Denso ECU is a locked Toyota platform, and most models do not respond to standard chip tuning. Low-output Toyotas are naturally aspirated city cars, where Stage 1 is limited by the high compression ratio. Toyota's factory tuning runs close to the limit, leaving only modest headroom for Stage 1.
