Pre-Dyno Checklist

Please review and complete this checklist before your dyno appointment.

If you have questions about your setup, or need any of these serviced performed on this list to be dyno ready, contact us before your appointment

Safety is our top priority—if any of these issues are present, the tune may be delayed or rescheduled.

1. Vehicle & Safety Readiness

Active Check Engine Lights or Mechanical Issues

• We will scan the car for any stored or pending codes.

• If any critical faults exist (misfires, sensor failures, knock codes), we must address them before tuning.

No Major Engine Noises

• No excessive knocking, ticking, grinding, or rattling sounds.

• No rough idle, hesitation, or surging under normal operation.

No Oil, Fuel, or Coolant Leaks (CRITICAL)

• Inspect the entire engine bay, turbo, and undercarriage for any signs of leaks.

• Ensure valve cover, timing cover, turbo oil feed/return, and oil pan are leak-free.

• No fuel leaks from injectors, fuel lines, or rails—fuel leaks = no tune.

• Ensure all coolant hoses, radiator, and reservoir are in good shape with no leaks.

Cooling System in Good Condition

• No overheating issues. Car must maintain proper operating temps.

• Coolant system must be full and bled properly (no air pockets).

• Radiator fans working properly.

• Upgraded cooling systems recommended for high-power setups.

Engine Oil is Fresh & Full

• Highly recommended: fresh synthetic oil change before tuning (especially for turbo cars).

• Oil should be clean, at the correct level, and free of contamination (fuel/coolant mixing).

Compression & Leak Down Test (For High Mileage or Built Engines)

• Any built engines or high-mileage setups should have compression/leak-down tests completed before tuning to confirm engine health.

Brakes & Tires Are in Safe Condition

• Ensure brakes function properly, with no grinding, pulsing, or spongy pedal feel.

• Tires must be in good condition with no visible damage or excessive wear.

No Fuel Starvation Issues (For High-HP / E85 Setups)

• For E85 or high-power builds, ensure the fuel pump, injectors, and fuel lines are adequate.

• Upgraded fuel pump and fuel pressure regulator required for full E85 conversions.

Battery & Electrical System in Good Health

• Battery should be in good condition—no weak starts or voltage drops.

• All ground connections must be secure to avoid tuning interference.

Wideband AFR & Boost Gauge Recommended

• A working wideband AFR gauge is highly recommended to be installed on the car for logging air/fuel ratios. (We have a wideband on the dyno for accurate reading)

• A boost gauge or electronic boost monitoring system is recommended to be installed for turbo setups. (We have a boost reading reference for accuracy)

Drivetrain is in Good Condition

• No clutch slipping (for manual cars).

• Transmission shifts properly (manual or automatic).

• Driveshafts, axles, and differential must be in good shape.

Secure & Safe Aftermarket Modifications

• All aftermarket parts must be properly installed with no leaks, loose fittings, or missing hardware.

• All vacuum lines must be secured with clamps or zip ties to prevent boost leaks.

2. Turbo & Boost System Check

No Boost or Vacuum Leaks

• Pressure test the system if possible. Any leaks will cause tuning issues.

• All couplers, clamps, and intercooler piping must be secured properly.

Turbocharger Health

• No excessive shaft play or grinding noises.

• Wastegate and bypass valve must function properly with no sticking or excessive flutter.

Exhaust System Free of Major Leaks

• No excessive exhaust leaks near the turbo, downpipe, or manifold.

• O2 sensors must be installed and functioning properly.

3. Fuel System & Tune Readiness

Fuel Type Ready (Pump Gas or E85)

• If running E85, ensure the fuel system is upgraded properly.

• 91/93 octane required for pump gas tuning—no low-grade fuel!

Fuel Pump & Injectors Are in Good Condition

• No misfires or weak fuel pressure issues.

• If running bigger injectors or fuel pump, ensure they are installed and working correctly.

MAF / MAP Sensor is Working Properly

• Sensor must be clean and in proper working order.

• If using speed density, ensure proper IAT sensor placement.

Throttle Body & Intake System Are Secure

• No leaks, no loose clamps or improperly installed sensors.

ECU / Tuning Software Ready

• If tuning remotely, ensure a stable laptop setup and proper software installed.

• If tuning in-person, have all necessary cables and licenses ready.
