Diesel Performance for 2014 GMC Sierra 1500

Diesel Truck Performance Parts & Tuning

If you own a diesel truck, you know how important it is to get the best possible performance, reliability, and efficiency from your vehicle. Whether you use your truck for towing, off-roading, daily driving, or all of the above, upgrading with performance parts and custom tuning can make a huge difference. At Lake City Performance, we specialize in helping diesel owners unlock their truck’s full potential with top brands and proven solutions like AMDP, Motor OPS, and Proven Diesel. From diesel delete kits to advanced tuning and SOTF (Shift-On-The-Fly) options, we have everything you need to take your truck to the next level.

Why Upgrade Your Diesel Truck?

Modern diesel trucks are built to handle tough jobs, but factory settings often leave a lot of untapped potential. Emissions controls, conservative engine calibrations, and stock parts can limit power and throttle response. Upgrading your diesel truck with performance parts and tuning isn’t just about going faster—it’s about making your truck work better for you. You’ll notice quicker acceleration, stronger towing capability, improved fuel economy, and sometimes even a smoother, quieter ride.

AMDP: Advanced Diesel Tuning and Deletes

AM Diesel Performance is a leader in custom diesel tuning and delete solutions for popular truck platforms like Ford Powerstroke, Ram Cummins, and GM Duramax. AMDP’s tunes are designed to safely increase horsepower and torque, improve throttle response, and optimize your truck’s shifting. Whether you want a mild daily driver tune or a full performance setup, AMDP has options to suit your needs.

One of AMDP’s specialties is diesel delete kits, which remove restrictive emissions equipment like the EGR (Exhaust Gas Recirculation) system and DPF (Diesel Particulate Filter). These deletes can help your engine run cooler, last longer, and make more power—especially when paired with custom tuning. Just remember, deletes are for off-road and competition use only and may not be legal for street use in all areas.

Motor OPS: Professional-Grade Tuning for Power and Reliability

Motor OPS is another top name in diesel tuning, offering advanced calibrations for GM, Ford, and Ram trucks. Motor OPS tunes are known for their balance of power, reliability, and drivability. Whether you’re towing a heavy trailer or just want a truck that feels more responsive, Motor OPS has you covered.

Motor OPS also supports popular tuning platforms like HP Tuners and EFI Live, so you can get custom tunes tailored to your exact truck and setup. Their SOTF (Shift-On-The-Fly) tuning lets you switch between different power levels while driving, which is perfect for changing conditions or sharing the truck with multiple drivers. SOTF is a game-changer for anyone who needs flexibility—go from economy mode to full power with the turn of a knob or press of a button.

Proven Diesel: Trusted Tuning and Performance Parts

Proven Diesel offers a wide range of tuning solutions and performance parts for diesel trucks. Their custom tunes are designed to maximize horsepower and torque without sacrificing reliability. Proven Diesel is a favorite among truck owners who want safe, dependable power for towing, daily driving, or performance builds.

In addition to custom tuning, Proven Diesel provides EGR delete kits, SOTF switches, and other parts that help your truck run cleaner and stronger. Their products are tested for quality and durability, so you can trust them to stand up to tough use.

Diesel Delete Kits: EGR, DPF, and More

Diesel delete kits are popular upgrades for off-road and competition trucks. By removing emissions equipment like the EGR and DPF, you can reduce exhaust temperatures, prevent clogging issues, and unlock more power. EGR delete kits stop hot exhaust gases from recirculating into the intake, which can help your engine run cleaner and cooler.

While deletes can offer big benefits, it’s important to know the laws in your area. In many places, deleting emissions equipment is only legal for off-road or competition use. Always check local regulations before installing a delete kit.

SOTF (Shift-On-The-Fly) Tuning: Power at Your Fingertips

SOTF tuning is one of the most exciting advances in diesel performance. With SOTF, you can switch between multiple power levels on the fly—no need to reprogram your truck or stop to change settings. This is perfect for drivers who need different tunes for towing, daily driving, or performance.

AMDP, Motor OPS, and Proven Diesel all offer SOTF options for popular trucks. The SOTF switch is usually mounted inside your cab and lets you dial in the right amount of power for any situation. Whether you want maximum fuel economy on the highway or full power for passing and towing, SOTF gives you control.
