The Banks Six-Gun diesel tuner for Duramax pickups allows truck owners
to select from six levels of power increases of up to 128 hp and 345
lb-ft torque while on the road. The Six-Gun is made to change the
truck’s output at the twist of a dial. The design combines all tuning
elements, pulse width, timing and fuel pressure into one tuner,
according to the company. Versions of the Six-Gun are also on the
horizon for the Ford 6.0-liter and Dodge 5.9-liter diesel engines.
