ISB PICKUP: Git-Kit includes the complete Monster Exhaust plus Banks OttoMind Diesel Tuner, which works with the Cummins electronic control unit (ECU) to properly calibrate fuel delivery and injection timing at all times. Git-Kit includes a host of electronic powertrain safeguards, and adds an assertive punch to your Cummins' performance. Git-Kit's gains of +65 hp and +170 lb-ft torque, plus 5% better mileage, produce big action at a small price. Test vehicle: 1999 quad-cab 4-wheel drive pickup 215-hp rated; automatic transmission. *Vehicles with higher rated engines: while the percentage gains will be less, the final power and performance output will be equivalent. Horsepower and torque measured at rear wheels. Lift-pump test-gauge kit is optional with Banks Stinger and Git-Kit, but included with Stinger-Plus and PowerPack systems.
