Turbochargers

The 2003-2007 5.9 Cummins turbo section is where stock replacements, Super B style upgrades, Aurora-style turbos, compound kits, and install hardware come together. This is where towing setups and performance builds start to split paths.

A single charger for towing needs quick spool and good EGT control, while compound setups need to be matched to fueling and transmission strength. Do not choose the turbo in isolation if injectors, tuning, or exhaust are being changed too.
