When Should You Switch to Speed Density? Here’s What You Need to Know
If you’ve ever installed a cam, added a supercharger, or made serious performance upgrades to your vehicle, you’ve probably asked yourself:
“Do I need to switch to speed density tuning now?”
In the latest episode of our On the Dyno series, Bob Morreale breaks it all down in plain English. This video isn’t just a theory lesson — it includes real student examples, data logs, and best practices for deciding when to keep your MAF sensor vs. when it’s time to go full speed density.
What You’ll Learn:
-
What speed density really is, and how it differs from MAF-based tuning
-
The biggest myth: why most people jump to speed density too soon
-
A real student case study showing how poor MAF placement caused massive turbulence and bad drivability
-
How to correct MAF issues by adjusting location and adding proper filtration
-
An example of a 1000 HP C6 Corvette where speed density was truly necessary
-
Why you shouldn't "scale" a MAF beyond 20–30% due to resolution loss
-
What a full speed density conversion looks like — including MAP sensor upgrades and tuning workload
