The 6.7L Power Stroke is the most powerful Super Duty diesel Ford has built, and it comes from the factory with more power than most owners will ever need to tow. That matters, because we do not carry an engine tuner for the 6.7 Power Stroke that is covered by a CARB Executive Order. So the legal performance path on these trucks is about airflow, lower temperatures under load, fuel system protection and a transmission that stays cool and strong. This guide lays out Stage 1 and Stage 2 for each year range, each with a towing build and a max power build.
Pick your truck below to see only the parts that fit it. Every card shows the fitment as it appears on the product page, and parts listed with a CARB Executive Order carry a green badge with the EO number.
Start with a healthy truck. Change both fuel filters, check both cooling systems, and make sure the DEF system and regenerations are working without faults. On 2011-2014 trucks, listen for turbo noise before adding any load. A protected fuel system matters more than any power part on these trucks.
Tuning and some performance parts can affect your factory powertrain warranty. Check before you install.

Every number below is a factory rating at the crank or a typical figure at the wheels, as noted. "Reliable towing target" is where we suggest a truck that tows stops, so the engine, transmission and cooling system all live a long time.
| Years | Stock rating | Transmissions | Reliable towing target | First limit you hit |
|---|---|---|---|---|
| 2011-2016 | 390-440 hp, 735-860 lb-ft (rose over these years) | 6R140 automatic | Factory power with lower temperatures and a protected fuel system | The CP4 fuel pump, and the 2011-2014 turbo |
| 2017-2019 | 440-450 hp, 925-935 lb-ft | 6R140 automatic | Factory power with lower temperatures and a protected fuel system | The CP4 fuel pump |
| 2020-2022 | 475 hp, 1,050 lb-ft | 10R140 10-speed automatic | Factory power with lower temperatures and a protected fuel system | The fuel pump, and heat in the 10R140 |
| 2023-2024 | 475 hp, 1,050 lb-ft; High Output: 500 hp, 1,200 lb-ft | 10R140 10-speed automatic | Factory power with lower temperatures and a protected fuel system | The fuel pump, and heat in the 10R140 |
Stage 1 is the bolt-on step: tuning (where a legal option exists), better airflow and the gauges to watch what the engine is doing. The towing build is what we recommend for most trucks. The max power build adds the parts that let the same truck make more power without giving up reliability.
Stage 1 on a 6.7 Power Stroke is airflow and monitoring. An S&B intake covered by a CARB EO, factory-style intercooler pipes that will not split under boost, and a monitor for exhaust and transmission temperature help the truck hold power on a long pull. Gains are modest, but towing temperatures come down.

Added power means added heat. These are the numbers to watch on your gauges while towing. They are sustained readings, not short spikes on a hill.
| Reading | Normal while towing | When to act |
|---|---|---|
| EGT (probe before the turbo) | Under about 1,200°F sustained | Back off or downshift if it stays above 1,250°F. On trucks with a particulate filter, sustained heat above that risks the filter. |
| EGT (probe after the turbo) | Reads about 200-300°F lower than a pre-turbo probe | Know which probe your gauge uses before you set an alarm. |
| Transmission fluid | 170-200°F | Act at 210-225°F sustained: slow down, downshift, add cooling. |
| Coolant | 195-220°F | Act if it stays over 225°F. |
| Engine oil | 210-240°F | Act at 250°F or more, sustained. |
Every part in this guide keeps your truck's factory emissions equipment in place and working. Where a part is listed with a California Air Resources Board Executive Order (CARB EO), the card says so. That EO exempts the part from California's tampering law (Vehicle Code 27156) for the vehicles it lists. An EO covers only the exact part numbers, years and engines it lists, and an EO for a tuner covers only the maker's preloaded tunes: a custom tune is not covered. Each EO covers its part by itself; CARB has not evaluated combinations of tuned parts. Parts marked "No CARB EO" are not legal for sale or use in California on pollution-controlled vehicles. Exhaust that bolts on behind the catalytic converter or particulate filter generally does not need an EO, but local noise rules still apply.
These trucks have EGR, an oxidation catalyst, a particulate filter and SCR with DEF. Keep all of it. We do not carry an engine tuner covered by a CARB EO for these trucks, so this guide does not include one. A few modules are covered for 2011-2019 trucks; ask our sales team.

A little, and it helps the truck hold its power on long pulls by lowering intake and exhaust temperatures. Pair it with intercooler upgrades for the biggest effect while towing.
At factory power, keep the fluid fresh and the transmission cool. For heavy daily towing, a converter and valve body (6R140) or a stronger converter (10R140) add margin.
