More power and fuel econumy

If an option pull the max force and drop in a cat.

 

But really, get all limiters turned off, then get the engine tuned electronically, and get a bullydog or Pittsburg power box if they make those for the maxxforce. Also, you can do upgrades to the motor itself but that will get pricey.
Last but not least, you shouldn't have bought a maxxforce.

 

If you're a company driver then you need to change jobs.

 

Bully dog gt aren't available on maxxforce engines.

 

Which maxxforce engine is it? 1st gen or 2nd gen?

 

Any of maxxforces
