can you do without the maf when custom tuning your own computer?? do i really need the maf enough to leave it?

yes... its called running in Speed Density..
your vehicle does not require a MAF to work...

MAF vs Speed Density you will get the same amount of power and torque... there is no difference in overall power numbers...

Nope, using a MAF is just easier.

the only differences come in throttle response..

because of how they work...
MAF typically will be a smoother more linear throttle response feel...it always feels a little sluggish compared to SD.
SD will typically be faster and more crisp, but is not as forgiving as a MAF and can feel jumpy/twitchy if not tuned correctly

Irrelevant really for an lsx engine as during high delta throttle inputs even a MAF car will use SD calculations to calculate airflow

not irrelevant.....
many factors in determining when MAF is used or not...

and in newer PCM's its used as 100% MAF with a virtual VE as a backup(which some can be changed to a real VE with a custom OS)


yes... during high throttle position changes it goes to SD, but you can change factors to make it more MAF dependent or less MAF dependent as you see fit based on vehicle mods.
