Tuning You Can Bet a Build On.
The difference between ‘it felt fast’ and ‘it always delivers.
Our Philosophy:
Science-Driven. Race-Tested.
Always Repeatable.
At Esse Werks, we don’t just tune—we engineer results. `Our calibrations aren’t wild guesses or “feel-based”—they’re precise, math-driven, and backed by testing.
“We don’t guess. We verify. That’s the difference.”
It’s the difference between sculpting a port by hand and programming a CNC:
repeatable, scalable, trusted.
This Is How Professionals Tune
Most tuners skip steps. We built a system—because consistent power requires consistent methods.
Baseline & Profiling
We read the full map, assess the build, and document every detail.
Pre-Tune Optimization
Mechanical and sensor health checks—no tuning over problems.
Math-Driven Adjustments
Every parameter calculated, not guessed—because the numbers don’t lie.
Iteration & Testing
Logged, analyzed, refined—each revision builds on the last.
Final Validation
Performance meets safety. We tune for long-term, repeatable success.
Consistency vs. Chaos
What separates a real tuner from a lucky pull?
Most tuners chase screenshots. One great pull, then it falls apart on the street—heat, fuel, conditions.
At Esse Werks, we don’t tune for moments—we tune for margins.
We create broad, stable powerbands. Power that repeats, not power that spikes and disappears.
You get control, not chaos.
Repeatability, not randomness.
Results, not regret.
Because one great pull doesn’t win the race. Consistency does.
Testimonials
What Owners Say After the First Pull… and the 100th.
“Not gonna lie... this base tune feels better and better every day!!”
“The tune is off the hook! It met my expectations! This is what I definitely expected from a e50 tune!”
Power Isn’t Random.
Neither Are Our Bundles.
Each of these tuner-curated packages includes the parts that unlock tuning headroom — and the calibration that makes it all work together.
No guesswork. No mismatched parts. Just repeatable, optimized power.
B-Series
Cold Spark + Tune
Starts at $499
Unlock smoother combustion and greater ignition stability with colder heat range spark plug upgrade—designed specifically for tuned BMW and MINI B-series engines. Paired with a custom calibration, this combo supports safer ignition advance, reduces knock under load, and lays the groundwork for bigger power gains down the line.
Whether you’re going Stage 1 now or prepping for a turbo upgrade later, this is the smartest first step.
Turbo + Tune
Performance Bundle
Starts at $1299
Maximize airflow and boost potential with an upgraded turbo matched to a custom tune. Whether it’s a hybrid drop-in or full-frame upgrade, we dial in the power curve, spool characteristics, and safety margins to make it drivable, reliable, and fast.
Includes support for boost control tuning, fuel system recalibration (if applicable), and proper logging as well as a custom spec turbo to match your vehicle’s goals.
Intercooler + Tune
Cooling Bundle
Starts at $799
Cooler air = more power. This bundle combines a high-efficiency front-mount intercooler upgrade with a tune calibrated for reduced IATs, more aggressive timing, and reliable repeatability—even under extreme driving conditions.
Perfect for cars running higher boost or living in hot climates.
Most Tuners Sell Power. We Deliver Control.
