Hauled my horses from Fort Worth up to Amarillo last month, got 17.8 empty on the way back. Was running around 13 before. Pulls a lot better up the grades too, didn't expect that part.

Used to go into regen every 280 miles when I was loaded down, now I'm pushing 580 with no regen at all. EGTs run way cooler too pulling the skid steer. Wish I had done this sooner, honestly.

Towing the boat down to the Keys used to kill me at 11 mpg. Got 15.4 last trip, same boat, same route. Pipe looks stock from the outside, none of my buddies even noticed it's gone.

Got four trucks on the ranch, did this one first to see how it'd go. Eight months in, no codes, pulls hay like she's new again. Other three are getting done before winter.

Bought it used and the previous guy had wiped the delete history clean. Got everything put back the right way, ran the protocol, passed smog first try. Truck finally drives like it should.

Running between three rig sites every week, was burning through DEF in about 2 weeks. Getting 6 weeks per jug now. Regen lockouts used to cost me half a day in the field, that's done with.
Why your dealer can't fix it
You did everything right. The truck was built to fail anyway.
If your dealer's had your truck more than two weeks this year — you're not the problem. You're the design.
Scene 1 · The Countdown
"5 MPH MAX. 150 MILES. SEE DEALER."
Dashboard lights up while you're towing the family at 70.
Scene 2 · The Phone Call
"$5,600 for the part. $1,000 labor. On backorder."
On a truck you already paid for. On a $200 sensor.
Scene 3 · The Wait
"Day 31. Day 16. Day 45."
Counting how long the dealer's had your truck this year.
You maintained it on schedule. You did the regens. You added the additive. You followed every recommendation in the owner's manual. And you still got stranded.
Every diesel built since 2007 runs three EPA-mandated systems — DPF, DEF/SCR, and EGR — that route your engine's own exhaust, soot, and chemistry back into the cylinders that just produced it.
Your engine wasn't engineered to run that way. It was engineered to breathe clean air, burn fuel, and expel exhaust — period. The factory bolted the failure point on at the end of the assembly line because it had to, not because it works.
That's why your dealer can't fix it. Every sensor he replaces buys you 18,000 miles before the next part in the chain fails. You weren't going to win this fight. The truck was engineered to lose it.
Ford doesn't know. The dealer doesn't know. We do — because we've torn down 10,000+ of these trucks across our 4 US shops and the failure pattern is identical every time.

Got Questions?
The stuff that keeps you up at night before you commit. Answered in plain talk by guys who actually wrench on these trucks.
A full mandrel-bent stainless DPF and CAT delete pipe, EGR block-off plates and gaskets, DEF delete components, all mounting hardware and clamps, and your preloaded tuner with the custom tune for your VIN. We don't ship anything you don't need, and we don't leave anything out that you do.
No. The custom tune disables the codes the deleted hardware would otherwise throw. Dash stays clean. If a real fault code pops up after install, call our line and a tech walks you through it. Usually it's a sensor that got unplugged during the wrench work, takes 5 minutes to sort out.
We pull your VIN before we ship. Engine, year, trim, cab config, all verified against the kit. If it doesn't fit your truck, you send it back and we either ship the right kit or refund you in full. Fitment is on us, not you. That's why we call it a fitment guarantee.
Most of our customers do. Average install is 2 to 4 hours with basic hand tools, sockets, ratchet, jack stands. You'll get the step-by-step install video emailed after purchase and a 24/7 phone line if you get stuck. If you can change your own oil, you can run our protocol.
Real custom files. Built in-house by guys who've been turning wrenches and writing tunes on Cummins, Duramax, and Powerstroke platforms for years. Every tune is dialed to your year, your engine, and how you actually drive the truck. No outsourced generic tunes pulled off a shared drive.
Once we've got the base files for your platform, dialing it in for your specific truck takes about 20 minutes. Charging $300 for that didn't sit right with us. We'd rather give you the better experience and earn the call when your buddy's truck needs help.
You call us. Real diesel techs, US-based, picking up the phone. We help with install troubleshooting, tune adjustments, fitment issues, codes, anything. We don't disappear after the sale, and the line doesn't go to voicemail. Phone number is at the bottom of every email and on every page of this site.
Yes. The custom tune is reversible, flash the stock file back through your tuner and the truck reads as factory again. The only thing that's permanent is the deleted hardware itself, but most buyers in the diesel community see a properly executed delete as a value-add, not a deduction. We can also ship the OEM-style reverse plates if you want to put the factory exhaust back on for resale.
Lifetime warranty on the stainless delete pipe, no rust-through, no cracks, ever. 2-year warranty on the EGR delete plates, gaskets, and hardware. If anything fails, we ship a replacement same day. The tuner itself carries the manufacturer warranty through EZ Lynk or HP Tuners.
Orders ship from Fort Worth within 1 to 2 business days. Free express shipping anywhere in the lower 48. Most orders land in 3 to 5 days. You'll get tracking the second it leaves the shop.
