Myth #1 – Deleting or Tuning a Truck is Legal

There is no way around this; it is 100% illegal to tamper with or modify the emission system on your truck in any way. It isn’t a state or local law (although those exist, as well), but Federal law. When we mention this, the first thing customers say is that “it’s for off-highway use only” or “it’s for tractor pulls.” They have the idea in their head that this will allow them to skirt around any laws, and that's hardly the case.

Yes, you can legally have your emission system removed from your vehicle, but it requires recertification by the manufacturer and a new emission label and certification issued. You can’t just sign a piece of paper and proclaim you’ve re-certified your engine. You would need to go through the costly process of having your engine re-certified by the original equipment manufacturer.

Another common misconception among clients is that the EPA doesn't go after small businesses. For reference, the EPA provides a list, by year, of every single resolution that is brought up against the Clean Air Act for vehicles. You will find cases ranging from providers of tuning equipment being charged over $4 million to a single owner performing a DPF delete on one vehicle.
