A calibrate-to-order module; levels 1-4 are emissions legal; level 5 (up to +120 hp and +233 lb-ft at the rear wheels) is for high performance/racing use.
When nothing less than “more” will satisfy you, go with Banks Big Hoss Module. Big Hoss is a calibrate-to-order module, in up to 5 power levels (for '99-03 models), that adds up to +120 hp and +233 lb-ft (with recommended airflow improvements). A pyrometer is recommended (see the Gauge section under Instrumentation).
When you group the Big Hoss Module together
with other components you save even more money.

Just wanted to drop a note and let you know how much I appreciate your products.
In 2007, you installed an exhaust brake, Smart-Lock, Monster Exhaust and a chip (Big Hoss Module) in my 2001 Ford F-250 4x4.
This last November, my wife and I took the month off and traveled throughout Northern California, Western Nevada and the Eastern Sierra region of California with our 7,500-pound Prowler travel trailer in tow. We covered approximately 4,000 miles. The horsepower boost from the chip and exhaust was appreciated on the upgrades, and the exhaust brake more than earned its keep on the many long downgrades. I have never felt so in control of my rig!
Congratulations!!! Your equipment took what had been a good tow vehicles and made it an awesome tow vehicle!!! I have heartedly recommended your products to my other diesel pickup owning friends and clients.
If I ever wear out the '01, I'll be back for the same treatment for its replacement.
