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 โ logs โ ECM remap (tune) โ 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 linksโarrive 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 equipmentโcommonly 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 firstโphotos, videos, or a quick WhatsApp call are welcome. Weโre here to help, but itโs 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 mechanicโs 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 hazardousโno 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.
