DIESEL PERFORMANCE

BUILT FOR TEXAS.

Professional diesel performance upgrades in Moody, TX. From a simple tune to a full Stage 3 build, Braxton’s Diesel Works helps Central Texas truck owners get more power, better towing capability, and improved fuel economy from their diesel.

MORE POWER. BETTER TOWING. BUILT RIGHT.

Diesel trucks are capable machines right from the factory, but most have significant untapped potential. At Braxton’s Diesel Works in Moody, TX , we unlock that potential with performance upgrades that are engineered to work together — not just bolted on and hoped for the best.

Every performance build we do starts with a conversation about your goals. Are you looking for better fuel economy on the highway? More towing capacity for your trailer? Or are you building a truck that turns heads and moves? The answer changes what modifications make sense and in what order. We’ll give you an honest roadmap based on your specific truck, your budget, and your goals.

We use quality parts and professional tuning software on every build. We don’t sell you modifications that don’t work or that will cause problems down the road. Our reputation in Central TexasCentral Texas is built on doing things right, and that applies to performance work as much as anything else we do.

DIESEL PERFORMANCE SERVICES

From a single modification to a complete performance build, here’s what we offer at our Moody, TX diesel performance shop.

Custom Diesel Performance Tuning

A quality tune is the foundation of any diesel performance build. We use professional tuning software to optimize fuel delivery, timing, boost targets, and transmission shift points for your specific truck, driving style, and goals — whether that's towing, daily driving, or all-out performance.

Turbocharger Upgrades

Your factory turbo is designed for a balance of performance and longevity at stock power levels. When you're pushing more power, an upgraded turbo is often the most impactful single modification you can make. We source and install quality replacement and upgraded turbos for all major diesel platforms.

Cold Air Intake Installation

Diesel engines are air pumps at their core — more air means more power. A quality cold air intake improves airflow into the engine, reduces intake temperatures, and can improve throttle response and fuel economy. We install and tune for intake upgrades on all major diesel trucks.

Exhaust System Upgrades

Reducing exhaust backpressure allows your engine to breathe more freely and make more power. We install upgraded exhaust systems, downpipes, and DPF-back exhausts to complement your other performance modifications and give your diesel the sound and flow it deserves.

Intercooler Upgrades

Cooler charge air is denser charge air, and denser air means more power potential. An upgraded intercooler reduces intake air temperatures, which is especially important on tuned trucks making more boost than the factory intercooler was designed to handle.

Lift Pump & Fuel System Upgrades

High-performance diesel tunes demand a reliable fuel supply. A quality lift pump upgrade ensures your injection system always has the fuel volume and pressure it needs, protecting your expensive injectors and enabling consistent performance under load.

PERFORMANCE BUILD STAGES

We approach performance builds in stages so you can invest at a level that makes sense for your budget and goals, with a clear path to more if you want it later.

Estimated Gains

50-100 HP / 100-150 lb-ft TQ (varies by platform)

DIESEL PERFORMANCE FAQ

Will diesel performance upgrades void my truck's warranty?

This depends on your truck’s warranty status and the specific modifications involved. For trucks still under factory warranty, some modifications can affect warranty coverage on related components. We’ll discuss the warranty implications of any modification before we begin work so you can make an informed decision. For trucks out of warranty, this is generally not a concern.

Can I get a performance tune without any other modifications?

Yes — a tune alone is one of the most cost-effective performance upgrades available for a diesel truck. On most platforms, a quality tune can deliver 50-100 horsepower and 100-150 lb-ft of torque gains without any other modifications. We’ll discuss your goals and recommend the best approach for your truck and budget.

Will performance upgrades affect my diesel truck's reliability?

Done correctly with quality parts and a proper tune, performance upgrades can actually improve reliability in some cases by optimizing how the engine operates. The key is doing the right modifications in the right order, using quality parts, and having the tune dialed in by someone who knows diesel engines. We don’t cut corners on any of that.

What diesel trucks do you build performance upgrades for?

We build performance upgrades for all major diesel truck platforms, including Ford Power Stroke (6.0, 6.4, and 6.7), Chevrolet and GMC Duramax (LB7 through L5P), and Ram Cummins (5.9 and 6.7). Each platform has its own strengths, weaknesses, and upgrade paths, and we tailor our recommendations accordingly.

How much horsepower can I realistically add to my diesel truck?

That depends heavily on your platform, your budget, and how far you want to go. A basic tune and intake on most modern diesel trucks will add 50-100 horsepower. A full Stage 3 build with turbo, intercooler, fuel system, exhaust, and tune can add 200-400+ horsepower on the right platform. We’ll give you realistic expectations based on your specific truck and goals.

Do I need to upgrade my transmission for a performance build?

For mild Stage 1 builds, most factory transmissions handle the added power without issue. As you push into higher power levels, transmission upgrades become increasingly important to protect your drivetrain investment. We’ll flag this as part of our build planning conversation so you’re not surprised down the road.
