Introduction to DBOYSCUSTOMS LLC and Automotive Tuning

DBOYSCUSTOMS LLC is a Yukon, Oklahoma-based performance tuning and custom remapping shop established in 2018. Located in Yukon, OK, we specialize in high-quality, reliable tuning services across domestic platforms — GM tuning, Ford (Coyote) tuning, Dodge tuning, LS and LT swap tuning, transmission tuning, engine tuning, and mobile performance tuning for customers who prefer service at their location.


Whether you drive a daily driver, a weekend racer, or a fully built race car, DBOYSCUSTOMS combines industry-leading software, experienced calibration engineers, and road testing to deliver optimized power, drivability, and reliability.

Why Professional Tuning Matters

Modern engine control units (ECUs) are complex systems. Factory calibrations prioritize emissions, fuel economy, and broad useability for millions of vehicles. That means there is vast untapped potential in any performance-focused build — turbochargers, superchargers, upgraded fuel systems, swapped engines, or performance transmissions.

Professional tuning extracts safe, repeatable power while preserving drivability and long-term reliability. An expert tune calibrates timing, fueling, boost control, torque management, and transmission behavior to match hardware and fuel quality. Ignoring tuning after modifications invites poor performance, knock events, limp modes, and potential mechanical failure. DBOYSCUSTOMS provides custom remapping and performance diagnostics to ensure your investment performs as intended.

Our Approach and Capabilities

How DBOYSCUSTOMS Can Help

DBOYSCUSTOMS approaches each vehicle with a structured workflow designed to reduce risk and achieve measurable gains:

1

Intake & Assessment

We document the vehicle, hardware changes, fuel type, and owner goals. This includes copies of current ECU files and hardware list (turbocharger, injectors, fuel pump, cams, etc.). 

2

Baseline Measurements

We use dyno runs, wideband AFR logging, and road data logging to capture baseline performance, fueling, and knock sensitivity. Diagnostics identify potential mechanical or sensor issues before calibration. 

3

Custom Remap & Calibration

We document the vehicle, hardware changes, fuel type, and owner goals. This includes copies of current ECU files and hardware list (turbocharger, injectors, fuel pump, cams, etc.). 

4

Safety & Protections

We implement conservative safety limits, knock detection strategies, and fuel-cut protections. Thermal strategies for turbo or supercharged systems are tuned for real-world conditions. 

5

Validation & Tuning Iterations

Each tune is validated with additional dyno or road runs. We refine parameters to achieve target AFRs, stable timing, and consistent performance under load. 

6

Delivery & Support

Each customer receives recommended octane and guidance on fueling. We provide follow-up support for logging and fine-tuning.

Why Local Vehicle Owners Trust DBOYSCUSTOMS

Local drivers and racers in Yukon and the greater Oklahoma City area choose DBOYSCUSTOMS because we combine real-world experience with methodical calibration techniques. Our shop uses modern ECU tuning tools, reliable logging hardware, and an evidence-based approach to boost control and ignition timing.

We provide honest assessments, realistic power expectations, and practical recommendations tailored to your budget and goals.

Frequently Asked Questions

  • How long does a tune take?

    Standard performance tunes typically take 2–6 hours depending on vehicle complexity, required dyno time, and whether modifications like injectors or turbo upgrades need compensating maps. Swapped engines and transmission calibrations often require additional time for initial setup and testing.

  • Do you offer mobile tuning?

    Yes. Our mobile performance tuning service delivers on-site diagnostics, logging, and flash-based remapping for customers within our service area. Mobile tuning is ideal for customers with limited transport options or for on-track tuning sessions.

  • Will tuning void my warranty?

    Any aftermarket tuning may affect manufacturer warranties. We advise customers about potential warranty impacts and offer strategies that minimize risk. For highly modified cars, warranty coverage may already be limited.

  • What fuel should I use after a tune?

    Fuel recommendations depend on the tune and hardware. Many performance tunes require higher-octane fuel (91–93 AKI) or race fuel for peak timing and safety. We always document recommended octane and fueling strategies.

  • Do you support custom engine swaps (LS/LT/Coyote)?

    Yes. We specialize in LS and LT swaps as well as Coyote integration, offering engine management adaptation, cam/crank synchronization, and drivability calibration to ensure clean starts, stable idle, and smooth driving behavior.
