Six-Gun Diesel Tuner
2004-2005 Chevy 6.6L; LLY
Optimum fuel tuning for awesome power, built-in safety and adjust-on-the-fly power, plus temperature limiting control w/optional Temp Limit Kit. Tuning that doesn't kill the host vehicle. Many tuners reduce fuel delivery as exhaust gas temps rise. But they ignore the powertrain! Banks finds the limits of the engine and powertrain, then adds mission-critical ActiveSafety safeguards to Six-Gun so it won't exceed those limits. As a result, Six-Gun thrashes challengers, not your truck! Airflow upgrades recommended. Proof of a higher power. Calibrated for sport applications, Six-Gun is a performance junkie that adds +102 hp/+275 lb-ft. With its CleanTune Technology and change-on-the-fly power, Six-Gun rockets you from 0-60 mph 24% quicker and 154 feet ahead of stock...without adding soot! All gains measured at the rear wheels, with recommended airflow improvements. Test vehicle: 2004 Chevrolet Silverado 2500, crew cab, long bed, single rear wheel. Engine: Duramax 6.6L LLY. Transmission: Allison 5-speed automatic. Horsepower and torque measured at rear wheels. Engine differences in 2004 vehicles: Early 2004 vehicles LB7 engine (8th VIN digit = '1'). Late 2004 vehicles LLY engine (8th VIN digit = '2'). Upgradeable options include Banks iQ & airflow components to build a complete engineered power system. For best Six-Gun Tuner performance, Banks always recommends airflow improvements.
