Engine starts and idles RequiredVehicle currently drives safely RequiredWhat must be completed at this appointment? RequiredWho built / wired the vehicle?

3. Engine, ECU, fuel & boost summary

Exact part numbers are preferred. Write UNKNOWN when the information is not available.

4. Goals & hard limits

Primary use RequiredPower / torque goalMaximum engine RPMMaximum boostRequired fuel / allowed rangeKnown engine / drivetrain limitTop priorities in orderFeatures requested / not requested

5. Previous tune & calibration history

This is especially important when another tuner has worked on the vehicle or hardware changed after the last known-good file.

Previous tuner / shopApprox. date last tunedOriginal / base map sourceCurrent calibration file name / revisionKnown-good older file available?Was previous tune finished?Fuel / ethanol used when last tunedBoost / RPM used when last tunedPrevious dyno type / facilityPrevious WHP / WTQ result

Most useful question: When did the vehicle last run correctly, and what changed immediately before it stopped running correctly?

When did it last run correctly?What changed immediately afterward?What do YOU believe is wrong with the current tune?What has a previous tuner / mechanic told you is wrong?

Meaningful calibration revisions

Add the changes you know about. You do not need to list every saved file.

Date / revision	What changed	Why	Result

6. Changes since the last known-good calibration

Anything else changed?

7. Known problems & failure history

Describe current or intermittent symptomsPrior overboost, detonation, lean event, sync loss, or tuning incident

8. Owner pre-dyno readiness checklist

Check items you have completed or had verified. If you cannot verify a safety-critical item, tell FEF Performance before the appointment.

9. Files & supporting information

Upload PDFs, images, CSV/log files, or ZIP archives. For ECU calibration files with uncommon extensions, place them in a ZIP first. Max total upload target: 20 MB.

10. Accuracy acknowledgement

Do not guess technical data. Wrong injector, pressure, trigger, fuel, sensor or boost-control information can make a starting calibration unsafe.

I answered accurately to the best of my knowledge, marked unknown information rather than guessing, and disclosed known safety/mechanical/tuning concerns.I understand this is a preliminary intake. If an authorization amount in the final Service Terms differs from this intake, the final signed Service Terms control.I understand that accepted jobs require the Service Terms / Liability Release to be completed electronically before appointment confirmation and signed again in wet ink by the owner or authorized signer upon arrival at the dyno facility before testing begins.
