VGT retrofits: Howler kits add vane control and exhaust brake; the controller/harness is required for HE351VE swaps.

Frequently Asked Questions

How does the BD Howler VGT compare to a drop-in Cheetah?

Howler VGT adds variable vanes and integrated exhaust brake for strong low-RPM spool and control, great for tow rigs. Cheetah is a stock-appearing, bolt-in turbo with a larger 63mm FMW compressor for quick spool and higher airflow without custom piping.

Which Cheetah fits my truck?

Use FPE-351-0304 on 2003–2004 (HE341) and FPE-351-0407 on 2004.5–2007 (HE351CW).

Do I need tuning after a turbo swap?

Many drop-ins run on stock tuning, but optimized fueling/timing improves drivability, EGT, and power. Always log EGT/boost and address fuel delivery.

What else should I upgrade with a larger turbo?

Prioritize a healthy lift pump and CP3, free-flowing exhaust/intercooler path, and essential gauges. Use new gaskets, V-band clamps, and an OE-quality oil feed line at install.
