Why We Dyno Every Car Before and After a Remap
The Short Answer
Because a number you measure is worth more than a number you’re promised. Every remap at MSL Performance starts with a baseline run on our own dyno in Al Quoz and finishes with a final run on the same dyno, so the gain is measured, not estimated.
You leave with a printed before-and-after result. That is the difference between a tuner and a file-seller.
What Is a Dyno?
A dynamometer, or dyno, measures the power and torque a car produces while it is driven under load in a controlled setting. It records the whole curve across the rev range, not just a single peak number.
Because conditions are controlled, runs can be repeated and compared, which is what makes it useful for tuning.
Why Start With a Baseline Run?
A baseline run shows the car’s real starting point. Two cars of the same model can produce different figures, depending on condition, fuel and specification.
The baseline also helps confirm the engine is healthy before anything is written. We don’t tune a car with an underlying fault.
What Happens Between the Two Runs?
The map is written to your car’s engine code, fuel grade and specification. It is then refined with live datalogging across multiple pulls: fuelling, ignition timing and, on turbocharged engines, boost are adjusted and checked against what the engine is actually doing.
Each pull gives the tuner data. Each change is checked against it.
Why Not Just Flash a File and Send the Car Home?
Some tuners sell a generic file, flash it on and never measure the result. Nobody knows how that engine is running under load, or whether the promised gain is real.
A dyno removes the guesswork. If something is not right, it shows on the dyno, not on the road.
What Does the Final Run Prove?
The final run, on the same dyno as the baseline, shows the measured gain in power and torque. It confirms the map is doing what it was written to do.
You get a printed before-and-after result to keep.
Can You Compare Dyno Figures Between Workshops?
Not reliably. Different dynos, and different conditions on the day, read differently. What is meaningful is a before-and-after comparison on the same dyno, which is exactly what a baseline and final run give you.
Results vary with vehicle condition, fuel grade and specification. Every figure we publish was measured on our dyno in Al Quoz.
What Should You Look For on a Dyno Sheet?
A useful dyno sheet shows:
- Before and after runs on the same sheet, from the same dyno.
- Full power and torque curves, not just peak figures.
- The car it relates to.
- The date of the runs.
A smooth curve across the rev range matters as much as the peak number.
The Same Discipline, at Every Level
The process is the same on every car that comes through our workshop in Al Quoz, Dubai: health check, baseline run, map written and refined, final run and handover.
It is the same team behind a verified McLaren 720S world record: 211.74 mph half-mile, as published by Dodson Motorsport.
Common Questions
Frequently Asked Questions
01 — Is a dyno run safe for my car?
Runs are carried out in a controlled setting, with the engine monitored throughout. The health check before the baseline run is part of keeping it that way.
02 — Do I get a copy of the results?
Yes. You get a printed before-and-after result to keep.
03 — Why are your figures different from manufacturer claims?
We publish what our dyno measures on the car in front of us, never manufacturer claims or estimates. Measured figures depend on the dyno, the conditions and the car itself.
04 — What is datalogging?
Datalogging records what the engine is doing during each pull, such as fuelling, timing and boost, so the tuner can see exactly how the map is behaving and refine it.
