Dyno Session Deposit — Reserve Your Slot

This deposit reserves shop time on our Mustang MD-500 load-bearing dyno for either dyno pulls (numbers & graphs) or dyno tuning (calibration work).

$300 deposit
$180/hr • 1-hr minimum
Deposit credited to invoice
2WD • Max width 80″

How Billing Works

$180/hr, 1-hour minimum, billed at the end of your session.
$300 deposit today to reserve your slot; it’s credited to your final invoice.
Any unused portion of the $300 deposit is refunded after we bill your time.
Deposit is non-refundable for cancellations/no-shows. You may reschedule once (subject to availability).

Please review our Dyno Day Prep before booking.

Just Dyno Pulls

Baseline runs for horsepower/torque numbers.
Verify different maps / switch-on-the-fly tunes.
Speedometer calibration and transmission shifting tests.
Wideband O2 and AFR safety check.
External knock sensors/monitors and/or EGT testing.
PDF graphs of each run included.

Perfect for comparisons, validation, or bragging rights.

Dyno Tuning

Baseline → logs → ECM remap (tune) → validation pulls.
Tuning is iterative: change, flash, test, repeat.
We try to finish same day; sometimes additional sessions are required.
You may need to return (billed time) for additional tuning.
Goal: stronger, safer, repeatable power.

For drivability (idle, cold start, part-throttle), add a Street Tune.

What to Expect on the Dyno

Baseline pull to document current HP/TQ.
Logging of AFR, ignition, and boost (if applicable) under controlled load.
Logging of knock activity for engine safety.
Emailed results of baseline and/or tuned pulls with PDF charts/datalogs.

Heads up: Pulls are performed in a high gear at high speed (often 120+ MPH). A chassis dyno will expose weak links—arrive prepared.

Vehicle Fitment

2WD only (no AWD at this time).
Max dyno width: 80″. Wide-stance trucks may not fit (we can street tune those).

Before You Book

Read the Dyno Day Prep Checklist.
Bring at least 1/2 tank of 93 octane (contact us first for E85/Flex setups).
Sign the Service Agreement.

Policies & Cancellations

Setup time is billable if you are a no-show. Dyno setup requires ~1 hour, and that setup charge will be billed from your deposit. Cancel at least 24 hours in advance to avoid the setup charge.

Vehicle acceptance is at our discretion. We will refuse any vehicle that presents a safety risk or threatens our equipment—commonly due to improper tires, damaged wheel studs, loose bodywork, fluid leaks, or poor workmanship.

Bring a safe, compliant car. If you arrive with an unsafe or non-compliant setup, you will forfeit your deposit. If you have any doubts, contact us first—photos, videos, or a quick WhatsApp call are welcome. We’re here to help, but it’s your responsibility to come correct.

Cleanup Fee. If your vehicle spills oil, gas, transmission fluid, coolant, or any other fluid on the dyno, a cleanup fee will be charged. The vehicle will not be released until the fee is paid in full. The fee is $460, which includes $100 in supplies (oil dry, PIG, Simple Green, mop heads, microfiber towels, etc.) plus 2 hours of labor for cleanup. There are no exceptions. If cleanup requires less time, we will refund the difference. However, under no circumstances will a vehicle be released until the cleanup fee is paid in advance.

Damage. If your vehicle causes damage to our equipment, you are financially responsible. Because the full extent of damages (capital repairs, lost revenue, downtime, etc.) is impossible to calculate at the time of failure, you agree in advance to liquidated damages in the amount of $5,000. This amount must be paid within 30 days, and must be paid before your vehicle will be released. If payment is not made, we will retain possession of your vehicle under the mechanic’s lien laws of the State of Georgia.

Engine Swaps & High-Performance Builds

Plan ahead to save time and cost. We are here to tune your vehicle, not complete unfinished builds. If we identify an issue (e.g., faulty sensor), you are welcome to repair it yourself on-site using your own tools (realistically, this usually means working in the parking lot). If you prefer not to handle repairs, our Dyno Prep work is billed at $220/hr. A typical 4-hour prep runs about $880 in labor, with parts billed separately. This service is limited to minor diagnostics and repairs involving electrical systems, engine sensors, fuel, ignition, and cooling systems, or corrections to weak points exposed on the dyno (commonly undersized fuel systems or poor-quality parts). Lead time will vary, and may not be the same day.

Shop Rules

Dyno pulls are hazardous—no spectators by the dyno during runs without a signed waiver.
We can set up a camera and grab a few clips on request.
Drop-off is welcome; keys can be left in the after-hours lockbox.

Payment Policy

Cash/Zelle pricing: All prices are quoted for payment with cash or Zelle.

We accept cards and app payments; if you choose one of those, divide the cash/Zelle price by 0.75 to get your total. Example: .

Use coupon code ZELLE at checkout when paying with Zelle to lock in the displayed price.

Message us with photos or a short video of your setup—we’ll confirm fitment and readiness before you book.
