How much horsepower can this turbo support?
The FPE-LML-VNT-63-FMW-N is rated up to approximately 650 RWHP with the correct supporting modifications and calibration.
Is this a direct bolt-on replacement?
Yes — this turbo is designed as a direct drop-in for the factory VNT turbo on 2011-2016 6.6L LML Duramax, using the stock housings and OEM connections when following proper installation procedures.
Does it maintain factory exhaust brake and VNT functions?
Yes — the variable nozzle technology is retained. The turbo acts small on spool-up and opens for high flow top end, keeping factory behaviors intact.
Is tuning required after installation?
While basic bolt-on operation may not require tuning, to fully exploit the airflow and support higher horsepower levels we highly recommend a quality calibration matched to your build.
California/Emissions status?
This turbo is legal under CARB EO D-834-3 for applicable applications in California. Always verify EO coverage for your exact model year/configuration.
