Tuned Vehicle Maintenance Checklist PDF | DD84

A Repeatable Maintenance Record for Tuned, Modified, Street, and Track Vehicles

Protect the work already invested in your vehicle with a printable DD84 checklist built around the items that matter on modified combinations.

Use it to create a consistent inspection routine, record tune-related details, and catch changes before they become expensive failures or confusing datalogs.

What the Checklist Helps You Track

• Engine oil, coolant, transmission fluid, leaks, belts, and hoses
• Tire pressure, lug torque, brakes, and basic safety checks
• Fuel type, ethanol content, fuel pressure, and fuel-system notes
• Tune version, datalog notes, wideband readings, knock, and temperature observations
• Pre-drive, pre-track, and post-event inspection reminders

Best For

• Street-driven performance vehicles
• Track, drag-and-drive, and race-weekend preparation
• Fresh builds, engine swaps, cam swaps, and vehicles with recent calibration changes
• Owners who want one consistent record instead of scattered notes
