An All-Wheel-Drive Mustang Dyno for Power Runs,
Custom Maps and Faults That Hide on the Street
Solo Motorsports runs its own Mustang dynamometer for dyno tuning near Atlanta, a 4WD unit that pushes back against the tires the way a long grade or a GA-400 on-ramp does. That matters for an all-wheel-drive Audi. And it matters for the number you take home. You can book dyno tests and dyno tunes through the Alpharetta, Downtown Atlanta, Johns Creek, and Norcross shops, and one session on the rollers will tell you more about the car than a month of forum threads.
Quick Takeaways
- Two services: a dyno test measures the car as it is, and a dyno tune rewrites the calibration between runs until it’s right.
- AWD welcome: the Mustang dynamometer is 4WD and load-bearing, so quattro, xDrive, and 4MATIC cars run with both axles turning.
- Quotes start with the car: send the mods and the fuel.
- What you take home: horsepower and torque curves, with boost and air-fuel ratio plotted against rpm.

A Dyno Test Measures the Car and a Dyno Tune Changes It
A test measures, and a tune calibrates between measurements. Book a dyno test when you want facts: what the car makes stock, what that new exhaust actually added, or why it goes flat above 5,000 rpm. Book a dyno tune when you want those numbers changed.
The two look nothing alike on the calendar. A test can be one run. Then a printout. A tune is a cycle of running, reading the logs, adjusting boost, fueling, and timing, then running again, repeated until the curve stops changing from one pull to the next. Same rollers. Much longer booking.
All-Wheel-Drive Cars Run With Both Axles Turning
This dyno takes all-wheel-drive cars. Not every dyno can. On a two-wheel-drive dyno, an AWD car has one axle spinning and the other standing still, and many drivetrains won’t handle that for long. Solo’s Mustang unit is 4WD, so the whole driveline turns and the car behaves like itself.
That covers Audi S and RS models, all-wheel-drive 911s, 4MATIC AMGs, and the ALL4 MINI Countryman. Rear-drive and front-drive cars? Same rollers.
The Baseline Run Often Finds Work Before the Tune
A first run on a modified car is as much an inspection as a measurement. Weak parts show up here first.
A clutch that slips the moment torque goes up. A misfire that only shows under load, or a fuel pump that can’t hold pressure at the top of a gear. Don’t tune around any of it. Fix it first, because a fresh map on a tired part only finds the weak spot faster.
Prepare the Car Before It Goes on the Rollers
A car is ready for the dyno when it’s healthy, fueled for the map, and honest about its history. Most of that is on you. It’s quick.
- Fill up with the fuel you’ll run: a map written on 93 is a 93 map, so don’t arrive on a tank of something else.
- Sort out warning lights first: if the check engine light is on, find out why before anyone adds boost.
- Write down every part: intake, exhaust, turbo, injectors, even the bolt-ons from before you bought the car.
- Look at the tires: cracked or corded rubber has no business at full throttle on rollers.
- Bring any old tune files: knowing what’s been flashed before saves time on the first pull.
Skip one of these and the session starts with a fix instead of a run.
Reading the Dyno Sheet You Take Home
The sheet you leave with shows horsepower and torque across the rev range, with boost and air-fuel ratio plotted against rpm. Shape first, peak second. A smooth torque curve over a steady air-fuel line means a healthy tune, and a jagged one with a dip at 4,500 rpm means the map needs another pass.
Those curves come from simulated road testing, which is how federal fuel-economy ratings get made too. In the lab, a car’s drive wheels sit on a dynamometer while a driver follows set routines, and the toughest of those cycles reaches 80 mph. No road needed.

Frequently Asked Questions
How much does a dyno tune cost?
No figure fits every car, because the parts list, the fuel, and the condition of the engine all change the job. Send the year, model, modifications, and fuel through the contact form to request a quote for your car.
Why does a Mustang dyno read lower than a Dynojet?
A Mustang dyno applies load, so the engine works against resistance the way it does on the road. An inertia dyno like a Dynojet measures how quickly the car spins a heavy drum, which usually produces a bigger figure. Neither is wrong, but only numbers from the same dyno are worth comparing.
Can I get a dyno test without a tune?
Yes. A baseline run works on any car, bone stock or tuned somewhere else, and it’s the quickest way to find out what a set of parts or someone else’s map is really delivering.
Can a dyno find problems a road test misses?
Yes. A dyno can hold the engine at one load and RPM for as long as it takes to read the logs, which no public road allows. An intermittent fault has far fewer places to hide.
Is a dyno tune worth it over a remote tune?
For a modified car, usually. Solo sells remote tuning products through its online store for owners who can’t reach the rollers, but a dyno tune gets tested under load on your own car, run after run.
