Located at Yukon, OK 73099, DBOYSCUSTOMS is a trusted choice for local drivers and racers seeking proven tuning expertise.
Our Story
From Enthusiasts to Professional TUning
DBOYSCUSTOMS began as a small group of car enthusiasts and technicians who recognized a gap between aftermarket parts and factory engine calibrations. As vehicles became more software-driven, it became clear that unlocking true performance required both hardware upgrades and precise ECU calibration. Starting in 2018, we invested in tuning tools, dyno access, and training to build a repeatable, data-driven approach to performance. Over the years, we’ve tuned hundreds of vehicles — from mild street builds to highly modified race cars — earning a reputation for reliable, safe, and powerful results.
Our Values & Commitment
Safety First
We tune with conservative safety margins and clear fail-safes, balancing power gains with engine and drivetrain longevity.
Measured Results
Our process is data-driven — baseline dyno runs, iterative tuning, and validation ensure consistent outcomes.
Transparency
We explain what the tune will do, expected gains, and any potential trade-offs. Customers leave with clear documentation and recommendations.
Customer Focus
Each project begins with your goals — whether improved daily drivability, track performance, or maximum power. We advise on realistic outcomes for your budget and hardware.
Community Support
We support local car clubs, track events, and customers with ongoing logging and tune refinement.
Our Team & Expertise
Our technicians and tuners bring specialized skills:
Calibration Engineers
Experienced in editing fuel maps, ignition timing, torque strategies, and boost control across multiple ECUs.
Diagnostic Specialists
Skilled at interpreting live data, detecting sensor issues, and preempting mechanical failings that compromise a tune.
Mobile Tuning Technicians
Equipped and trained to perform secure, reliable on-site tuning for customers who need flexible service.
Precision Tools & Process
DBOYSCUSTOMS uses industry-standard tuning and logging tools, as well as shop-calibrated dyno resources to validate mapping changes. Our process includes:
1
Pre-check and mechanical inspection to confirm sensors and hardware operate correctly.
2
Baseline logging and wide band tunning to capture factory behavior.
3
Custom remap tailored to your hardware — injectors, fuel pump, turbocharger/supercharger, camshafts, and swaps.
4
Iterative validation with logging under load and in real-world driving conditions.
5
Final documentation and recommendations on fuel, intervals, and modifications.
Why Our Approach Works
Because we calibrate around the complete vehicle system. Rather than applying generic maps, we match fueling, ignition, and torque to the exact combination of hardware and driver intent. That reduces surprises and delivers consistent, safe performance. Our emphasis on diagnostics prevents wasted tuning time on vehicles with mechanical issues that undermine gains.
Client Stories & Results
We measure success by repeat business and customer satisfaction. Typical results include:
Street Car Gains
Safe, repeatable 10–40% increases in horsepower and torque depending on hardware and fuel.
Forced Induction Builds
Optimized boost control and fuel delivery producing measurable power with robust safety margins.
Swapped Engines
Smooth idle, reliable starting, and clean drivability after LS/LT/Coyote swaps.
Transmission Tuning
Faster, smoother shifts with improved durability under increased torque.
Frequently Asked Questions
Do you tune for competition vehicles?
Yes. We offer race car tuning and provide specialized maps tuned for fuel type, track conditions, and class rules. We also support data acquisition for performance teams.
Can you tune my swapped engine?
We frequently perform LS/LT and Coyote swaps, developing custom calibrations for crank/cam sync, fueling, and ignition to ensure reliability and drivability.
How do I prepare my vehicle for a tune?
Ensure the vehicle is in good mechanical condition: functioning sensors and fresh fluids. We perform a pre-tune inspection to identify issues that could affect tuning.
