Dyno Tuning Services
Safe, repeatable power built for real drag and street-strip cars — not internet tunes.
What We Tune
Sho-Me Speed provides professional dyno tuning for high-performance street, strip, and race cars. Our focus is not just peak horsepower — it’s repeatability, drivability, and reliability under load.
We specialize in:
- LS platforms
- Aftermarket ECUs such Holley EFI (Terminator X, HP, Dominator, AEM, Halltech, Fueltech, FAST, ETC.)
- Boosted applications (turbo, supercharger, nitrous)
- Naturally aspirated performance builds
- Street/Strip setups
- Track Only Setups
Every tune is built from real data from your vehicle.
What Dyno Tuning Fixes
Customers come to us when:
- The car is inconsistent pass to pass
- AFRs aren’t stable
- Timing is unsafe or overly conservative
- The car surges or hesitates
- Boost control isn’t predictable
- Power falls off down track
Dyno tuning allows us to safely load the engine, verify fueling and ignition, and correct problems before they cost parts.
What’s Included
- Fuel mapping & AFR optimization
- Ignition timing optimization
- Boost control setup (if applicable)
- Sensor verification & calibration
- Drivability tuning
- Safe RPM & power limits
- Data review & recommendations
Most sessions last 1.5–3 hours, depending on setup complexity.
Expected Results
Every car is different, but most customers see:
- 20–60 HP gains (NA)
- 30–120+ HP gains (boosted)
- Improved throttle response
- Safer AFR & timing
- More consistent ETs

Pre- Tune Check List
To make sure your appointment is put to the most efficient
use, the following should be checked prior to visiting our dynamometer. Failure
to ensure that the following items are in proper working order will cause your
tune to be inaccurate and/or unsafe. Repairs that need to be made while on the
dynamometer are NOT part of your quoted tuning rates, and will be billed at our
normal hourly rate in addition to the tuning fee
Mechanical Check List:
- Engine Compression
- Vacuum, Intake manifold and intercooler sealed under
vacuum and pressure.
- Oil and water lines properly tightened
- Turbo does not have excessive shaft play (if applicable)
- Exhaust properly installed and leak free
- Wheels in good condition and properly balanced
- Vehicle properly aligned
- No leaks of any kind from the crankcase, cooling system,
transmission etc.
- Spark Plugs fresh and have the proper heat range
- Oil fresh and at the proper level
Fuel System:
- Fuel pump properly sized and in working order
- Fuel Injectors clean and fuel injector O-rings free from
leaks
- Fuel pressure regulator in good working order
- Fuel filter clean and functioning properly
- Fuel lines and hoses properly installed and of the proper
type/size
-MAKE SURE VEHICLE IS FULL OF FUEL
Driveline:
- Clutch working properly and able to handle the power you
plan on making
- Transmission working properly and filled with clean fluid
- Differentials working properly and filled with clean fluid
- Wheel bearings in good working order
- Brakes functioning properly and properly suited for your
power level
Electical:
- Check ALL vehicle grounds!
- Battery and alternator working properly
- No engine lights or codes, unless they are known and need
to be cut off due to no longer having that equipment on the vehicle
- Tuning connections hooked up and available, IE ALDL (if
applicable)
