Ford 4.6 3-Valve No Tune C.A.I. Question:

[2006 Mustang GT]

Looking at a 50 State Legal CAI by S&B. The device used an oiled cotton filter and claims a 46% increase in airflow over pleated paper filter and requires no tune.

Wouldn't the increase in air intake velocity (if the claimed gain is indeed true) benefit from a tune???

If so, what parameters would you alter???

Sure, and in theory no CAI requires a tune because the vehicle is going to trim + or - what it needs to (at least until it hits a hard limit if it's that bad) try and find stoich....14.67, 14.10, 13.85 etc etc.

For proper tuning of a CAI you'd need to log LTFT and or STFT and make the adjustments to the MAF curve.

Thank you! Im new to all this...

IMO, a no tune required CAI is not going to help much if any at all...especially on a 3V

There are legit gains available from some of the popular intakes with a matching tune.

Agreed... i like that its 50 state legal. They have a dynojet printout on the site and it made a modest power gain.
