BuildSpec is a planning and education tool, not a tuning service, safety certification, or substitute for professional inspection or calibration. Power figures, thresholds, part prices, and recommendations are conservative planning estimates that vary with hardware, fuel quality, calibration, engine condition, dyno type, market pricing, and environment. Year and application coverage is approximate; verify your exact chassis and options. Always confirm part compatibility, emissions legality, and professional tuning requirements with your tuner or builder before purchasing or making power.
