Will a DPF delete void my warranty?

Yes. Ford will not warranty any emissions-related or powertrain failures once they detect a delete. You're responsible for repairs. That said, deletes are extremely reliable and many owners run 100k+ miles trouble-free on delete setups.

What's the difference between H&S Mini Maxx and BullyDog BDX?

Both are solid tuners. H&S Mini Maxx is plug-and-play with preset tunes; BullyDog BDX gives you more customization and data logging. If you want simple and proven, go H&S. If you're a data nerd or want to fine-tune boost and timing, BDX wins. EZ Lynk sits in the middle with smartphone control and flexibility.

Can I delete just the DPF without the EGR?

Absolutely. A DPF delete alone will improve exhaust flow and fuel economy. However, most guys delete the EGR cooler too since it's a known weak point and heat reduction helps the engine breathe easier. You don't have to do both at once, but they work well together.

Will deleting hurt my fuel mileage?

No—it'll improve it. A tuned, deleted 6.7L typically gains 1-3 MPG depending on your driving style and what you've done. Fewer restrictions mean less work for the engine. Towing economy also climbs noticeably.

Do I need EGR delete if I'm only towing light loads?

Not strictly, but it's still worth doing. EGR cooler failures are common on 6.7Ls regardless of load. Deleting it eliminates that ticking time bomb and drops intake temps by 20-40 degrees. If you plan to keep the truck long-term, it's cheap insurance.

What year-specific kits do I need?

2011-2014 and 2015-2016 have different EGR configurations, so grab the kit matched to your truck's year. DPF deletes and tuners typically cover the whole 2011-2019 range. When ordering, double-check your VIN year against the product specs—fitment is everything.

Is EZ Lynk Auto Agent 3 compatible with all 6.7L Powerstrokes?

EZ Lynk covers 2008-2022 6.7L models, so yes—it works on your 2011-2016. The smartphone app lets you tune and monitor on the fly, which is clutch for testing different configurations without pulling over.
