Default What is F/I

The reason I ask is I'm going to replace my stock TB/Plenum with a Accufab TB/Plenum. Do I need a Lightning 90mm MAF? I'm running 19lb injectors and have PI heads and PI intake.

Forced Induction... Turbo, nitrous, superchargers...
And the answer is no.

So just recalibrate the stock MAF?

No you do not need to change the MAF or injectors with those upgrades. With forced induction, it is required to change them.



No recalibration is needed. Your computer will make the necessary adjustments on it's own.

It's fine for a non f/i motor.

A little,

but it's worth the $200 bucks and 20 minutes of your time.
