Fresh fuel is crucial for accurate dyno testing, with fuel over 2 months old potentially compromising results. For optimal tuning, ensure:

• Proper oil level and type (synthetic for broken-in engines, break-in oil for new builds)
• Aligned suspension and equalized tire pressure
• Full throttle operation verification
• Fresh O2 sensors, especially near turbochargers
• Correct wastegate spring selection for target boost levels
• Secure and properly routed boost control lines
• Verified MAP sensor and fuel pressure regulator connections
• No boost leaks in the system
• New fuel filter installation
• Clean fuel injectors for optimal flow
• Proper ground strap connections

For best tuning results, consider these methods:

1. In-person dyno tuning with qualified professional
2. Remote tuning with local dyno operator
3. Street tuning (least recommended due to safety concerns)

Key tuning elements include:

• Air/fuel ratios
• Timing tables
• Boost targets
• Safety parameters
• Spark plug selection and gapping
• ECU timing synchronization

Proper preparation ensures optimal results and prevents wasted time and money during your tuning session. A well-prepared vehicle can achieve significantly better performance gains while maintaining reliability.
