DBR Doors Up
DBR Doors Up is a open garage event where DBR High Performance opens their doors so spectators can come enjoy and experience what happens behind DBR closed doors! Check out our shop and see what we're working on behind the scenes!
PCM/TCM upgrades, custom EFI tuning and calibration, and Mainline hub dyno testing, all under one roof.


Your vehicle’s true potential is limited by conservative factory parameters. We provide full PCM and TCM upgrade services that expand your vehicle’s tuning range, giving you total command over fueling, timing, and shift points. Don’t settle for what the manufacturer thinks you need—take what the engine is actually capable of delivering.
Precision tuning starts with access. Our PCM/TCM upgrade service opens the door to the deepest levels of your vehicle’s calibration, allowing for seamless integration of high-performance tuning. Whether it’s sharpening shift firmness in the TCM or optimizing air-to-fuel ratios in the PCM, we give you the range to build the powertrain you actually want.


Tire slip and strapping variables are for the hobbyists. We utilize a Mainline Hub Dyno to bolt directly to your vehicle's DNA, delivering the most precise, repeatable data on the planet. Whether we’re dialing in a 2,000hp drag build or a street-sleeper, we eliminate the guesswork and find every hidden pony. If it doesn't show up here, it doesn't exist.
Precision tuning requires an environment of total control. Our Mainline Hub Dyno removes the inconsistencies of traditional roller systems, allowing for high-load testing and ultra-fine calibration without the risk of tire failure or traction loss. We don't just measure output; we refine the entire power curve for maximum efficiency and destructive acceleration.



Generic "canned" tunes have no place in a high-performance build. Our EFI calibration service provides a bespoke map tailored specifically to your vehicle’s unique footprint and fuel requirements. By manipulating complex timing and fueling tables with surgical precision, we extract peak efficiency and driveability that the factory never intended you to have.
A pile of high-end parts is just expensive metal until the calibration is right. We specialize in custom EFI tuning that transforms raw hardware into a synchronized powerhouse. From cold starts to wide-open throttle, we optimize every millisecond of your engine’s operation for maximum reliability and devastating power delivery. We don't just tune; we weaponize.
