Details
Engine: Stock 4.6 4V
Intake: BBK Cold Air Kit
Exhaust: Classic Design Concepts Side Pipes
Gears: 3.73
Computer: PPC Custom Tuned Using SCT Advantage III Software
Notes: The stock graph has a major dip in the air fuel ratio at around 5200 rpm. This is most likely caused by the computer going into a cat overtemp protection mode and dumping fuel to cool off the converters. The drop in afr also causes a large drop in horsepower and torque. Our custom tune actually runs the car cooler allowing the vehicle to stay out of cat protect mode while also picking up large gains in horsepower and torque. Especially at 5200 rpm.
