Will a delete kit void my warranty?

Yes. Ford considers any DPF or EGR removal a warranty violation. That said, modern tuners don't leave breadcrumbs—dealers often can't prove you've deleted. Your call on risk tolerance.

Do I need both a delete kit AND a tuner?

Mechanically, no—a delete works standalone. But without a tuner, your truck throws check-engine codes and runs in limp mode. A tuner (like BullyDog) tells the computer the emissions gear is still there, preventing fault codes. Run both for full performance.

How much power does a 2015-2016 6.7L Powerstroke gain from a delete?

Expect 40-80 hp and 80-120 lb-ft torque gain with a complete DPF and EGR delete, depending on supporting mods. A tuner alone adds 20-40 hp. Real gains show up most under load—towing, hauling, and off-idle response.

Can I delete just the DPF and keep the EGR?

Absolutely. Some guys run DPF-delete-only to stay lighter on emissions. EGR-only deletes are rarer because the EGR cooler is a known failure point—most delete it to eliminate that risk. Pick your battle.

What's the difference between a CCV delete and a full delete?

CCV (crankcase ventilation) deletes remove the system that recycles blow-by gases, reducing crankcase pressure and oil vapors. It's a small mod with real benefits—cleaner internals, less sludge. A full delete handles DPF and EGR too. CCV is often the warm-up move.

Will a delete affect my fuel mileage?

Short answer: probably not. Most guys see the same or slightly better economy because the truck breathes easier. You'll feel the power gain way more than you'll see it at the pump.

Is the 2015-2016 6.7L Powerstroke the same as 2011-2014 models?

Similar, but not identical. 2015-2016 got a DPF redesign and updated EGR routing. Always confirm your year range before buying—fit matters. Our collection is locked to 2015-2016 for a reason.
