Speed Density Tuning (Add-On)

📊 Speed Density Tuning (Add-On)

This add-on is required for vehicles running Speed Density (SD) or setups that no longer use a MAF sensor.

This includes:
• Rotated turbo setups  
• Blow-off valve (BOV) setups  
• MAF delete configurations  
• Any Speed Density conversion  

✔ Applies to BOTH:
• New tunes  
• Retunes  

⚠️ EJ Engines:
A Speed Density harness is REQUIRED.

⚠️ FA20 / FA24 Engines:
No harness is required.

Due to the increased complexity of tuning without a MAF sensor, this add-on is necessary to properly calibrate airflow, fueling, and drivability.

⚠️ Important:
If your setup requires Speed Density and this add-on is not selected, your order will be delayed until corrected.

This ensures your vehicle runs safely and correctly for your configuration.
