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.
Use FPE-351-0304 on 2003–2004 (HE341) and FPE-351-0407 on 2004.5–2007 (HE351CW).
Many drop-ins run on stock tuning, but optimized fueling/timing improves drivability, EGT, and power. Always log EGT/boost and address fuel delivery.
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.
