Reliability/MPG Map:This map is for clients who want to increase the MPG and reliability of their 4Runner. Lower boost pressure and increased MPG. Less stress to the engine and driveline. This will result in the truck having less power and torque. Ideal for commuters or those that are not concerned with making power. This map can use either 87, 91 or 93 octane. (Intended for 87 octane)

Towing/Overlanding Map: This map is for clients who have bigger wheels, tires, bumpers, roof top tents and other heady modifications. This map slightly increases torque and boost pressure to make up for the drag created by towing or added weight. This map can use either 87, 91 or 93 octane.

Boost Map: For our clients who want to get the most out of their turbocharger. Using 93 or 91(Western states where only 91 is available) octane fuel is mandatory for using this map. This will increase boost pressure and increase the trucks performance. 

ALL PURCHASED MAPS WILL COME WITH TRANSMISSION ADJUSTMENTS TO REMOVE THE GEAR HUNTING THAT IS COMMON WITH 4Runner. (AT ONLY). THIS CLEARLY DOES NOT APPLY TO THE MANUAL TRANSMISSION.

You can purchase multiple maps for your application. The COBB Accessport can store multiple maps that can be flashed at any time the use for the truck changes.
