Fiddle with your engine’s performance level to your heart’s content. The Bully Dog 6-Position 4-Bank Chip puts the power at your fingertips with the included in-cab adjustment knob. You get 6 settings of boosted performance for peeling-out at the limit line or hauling a trailer uphill.

Of the 6 settings, the 6-Position 4-Bank Chip includes a stock level and horsepower boost settings of 50, 75 and 100. Also, use the new high-idle level for better starts in cold weather; or, the valet setting that uses stock values with a 70 mph speed governor. Or, replace one level with an ignition-kill security setting.

Don’t fear overheating with your new-found power—the 6-Position 4-Bank Chip is designed to keep your EGT 50 to 100 degrees lower than other performance chips. Plus, the Bully Dog Chip is loaded with tranny-smart software to improve shift points and extend gear life.

Your 6-Position 4-Bank Chip comes with the in-cab switch and is backed by a 1-year warranty.
