ENGINE & FUEL PERFORMANCE

The core of every diesel build. ECM calibration determines how the engine makes power; the fuel system determines how long it sustains it. These two services are planned together — they directly affect every other service we perform.

Primary Service
ENGINE TUNING / ECM CALIBRATION

EFI Live and HP Tuners diesel calibration for Cummins, Duramax, and Power Stroke. Stage 1–4 tune files, tow calibrations, and compound turbo support. All tunes dyno-verified.

View Service → Critical Support
FUEL SYSTEM UPGRADES

FASS and AirDog lift pump installation. CP3 conversion for 2019+ 6.7 Cummins and CP4-equipped trucks. Injector refresh and injection pressure diagnostics.

View Service → System Build
TOWING PERFORMANCE PACKAGE

Tow tune, EGT monitoring, transmission, and fuel system built as one package. Three tiers: Tow Ready, Tow Built, and Tow Max for commercial-load trucks.

View Service →

FORCED INDUCTION & THERMAL MANAGEMENT

Turbocharger, intercooler, exhaust, cooling system, and air intake — the airside and thermal system of the diesel build. Each component affects the others; compound turbo builds require all five to be planned together.

High Output
TURBO & FORCED INDUCTION

S300/S400 compound turbo builds, single turbo upgrades, and compound charger setups for Cummins, Duramax, and Power Stroke. Full turbo system design.

View Service → Charge Air
INTERCOOLER UPGRADES

Front-mount and top-mount intercooler upgrades. Mandatory on compound turbo builds. 3" pipe upgrade and tune revision after install on all FMIC work.

View Service → EGT Management
EXHAUST SYSTEMS

4" downpipe-back and turbo-back exhaust for Cummins, Duramax, and Power Stroke. EGT monitored. Tune revision mandatory after every exhaust install.

View Service → Thermal
COOLING SYSTEM UPGRADES

Radiator upgrades, oil cooler service, and EGR cooler assessment for 6.4 PS and LML Duramax. DCA coolant filtration for 6.7 Cummins wet-sleeve engines.

View Service → Pre-Turbo Airflow
AIR INTAKE SYSTEMS

Cold air intake and high-flow filter upgrades. Required on compound turbo builds. Honest about the power numbers — intake is a system component, not a standalone add.

View Service →

DRIVETRAIN & CHASSIS

Transmission, axle, suspension, and wheels — the mechanical foundation that must keep pace with engine output. Drivetrain work is scoped at the same consultation as engine work. The weakest link decides what breaks first.

High Torque
TRANSMISSION UPGRADES

68RFE, Allison 1000, and 6R140 upgrades. Valve body, torque converter, and full Stage 2 builds. Transmission is planned before the tune — not after failure.

View Service → Rear End
DIFFERENTIAL & AXLE UPGRADES

Dana 60/70, Sterling 10.25/10.5, and AAM 14-bolt upgrades. Ring-and-pinion re-gear, locker installation, and bearing service for high-torque diesel builds.

View Service → Suspension
LIFT KITS & LEVELING

2"–4" diesel lift kits and leveling packages for Ram, Super Duty, and Silverado/Sierra HD. Alignment mandatory after every install — no exceptions.

View Service → Load-Rated Fitment
WHEELS & TIRES

Load Range E fitment for HD diesels. Hub-centric wheel selection in the correct bolt pattern — Ram 8×6.5", Super Duty 8×170mm, GM HD 8×180mm. Re-gear paired when needed.

Platform-Specific Builds

Every Build Is Platform-Specific.
Not Generic Diesel.

Ram 2500 / Ram 3500
CUMMINS

5.9 and 6.7 Cummins builds. CP4-to-CP3 mandatory on 2019+ 6.7. Stage 1–4 EFI Live tunes, compound turbo, and 68RFE / Aisin transmission upgrades.

View Platform → F-250 / F-350 Super Duty
POWER STROKE

6.4 and 6.7 Power Stroke builds. CP4-to-CP3 on 2011+ 6.7 PS. EGR cooler risk on 6.4. Stage 1–4 tunes, compound turbo, and 6R140 transmission upgrades.

View Platform → Silverado 2500 / Sierra 2500
DURAMAX

LBZ, LML, and L5P Duramax builds. LBZ S400 compound turbo. CP4 assessment on LML. L5P EFI Live calibration. Allison 1000 upgrades.

View Platform →

SPECIALTY & COMPETITION BUILDS

Sled pull, drag prep, and specialty platform work. These builds require a different approach from street and towing builds — the power targets, fueling limits, and component choices are purpose-built for the event.

Competition
SLED PULL PREP

Full sled pull build planning for diesel competition trucks. Compound turbo, high-pressure injection, transmission for max torque delivery, and a locker for traction. Purpose-built, class-specific.

View Service → Competition
DIESEL DRAG PREP

Diesel drag racing build preparation — launch calibration, transmission setup, converter stall, and short-run fueling optimization. Class-legal or outlaw, we scope for the track.

View Service →

SPECIALTY PLATFORMS

Beyond the core three platforms, we also work on light-duty diesel trucks and specialty Cummins-powered platforms.

Light Duty
FORD F-150 DIESEL

3.0L Power Stroke diesel F-150 performance work. Tune calibration, fuel system service, and towing package for the light-duty Power Stroke platform.

View Platform → Specialty Platform
NISSAN TITAN XD CUMMINS

5.0L Cummins V8 diesel Titan XD performance builds. Tune calibration, fuel system service, and the unique characteristics of this platform addressed directly.

Common Questions

Diesel Performance Services FAQ

How the consultation and build process work at Drop Forged Diesel.

Do I need to know what services I want before the consultation?+
No. The consultation is where we scope the build. You tell us what the truck is used for — daily, towing, sled pull, drag — and what the power or capability target is. We'll identify the right build path, flag any platform-specific risks (CP4 exposure, EGR cooler condition, transmission wear), and give you a staged build plan that sequences the work in the right order. You leave with a clear path rather than a parts list.
Do you work on all three diesel platforms — Cummins, Duramax, and Power Stroke?+
Yes. All three platforms and their sub-generations: 5.9 and 6.7 Cummins, LBZ / LML / L5P Duramax, and 6.4 / 6.7 Power Stroke. Each generation has different failure modes, different tuning tools, and different component ceilings. We work on all of them and we know the specific weak points of each.
Can I do one service now and add more later?+
Yes — most builds are staged across multiple visits. The consultation produces a staged plan with the high-priority or prerequisite work first. A tune before a fuel system upgrade, for example, doesn't hurt anything — but a high-power tune before addressing a failing CP4 on a 6.7 does. We tell you the right sequence and you execute it at whatever pace works for you.
Do you do engine-only work or is drivetrain service required?+
Engine-only work is absolutely available — a tune or fuel system upgrade doesn't require you to do any transmission or axle work. We assess the drivetrain at the consultation and tell you what we see. If the transmission is healthy for the power level you're building to, we say so. If it's borderline, we tell you that too. The decision is yours.
