The 6.4L Power Stroke uses piezoelectric injectors — the same technology as the LML Duramax — and S\u0026amp;S has engineered a full lineup specifically for this platform from stock replacement through 100% over stock, with internal piezo modifications included in every build spec.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWhat separates S\u0026amp;S 6.4L injectors from everything else on the market is the level of precision engineering behind every set. S\u0026amp;S uses a proprietary nozzle honing process for clean and consistent holes, with nozzles flow-matched to 1% variance per set using OE standards — Viscor SAE-J967 fluid, 40°C, 100 bar. Complete injectors are flow-matched to 3% variance per set at four different pressure and energizing points per injector, with injection profiles (rate shapes) aligned across the set. Injector build spec is custom-matched to the nozzle flow rate for each size — and critically for the piezo platform, every injector includes internal piezo modifications (piezo mod) to properly match the injector body to the nozzle flow rate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAvailable flow rates and their intended applications:\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-pre-wrap leading-[1.7]\"\u003e\u003cstrong\u003eStock (6.4F-00SAC \/ 6.4F-00SAC-SET)\u003c\/strong\u003e — Precision stock replacement with S\u0026amp;S nozzle honing and flow matching.
