There is no "tuning" in the maf calibration. It is programmed to have the same calibration as the stock maf. x flow = Y hz You can not change this and have the stock car run without a tune. This is the reason some aftermarket cold air systems need a tune. when you place the maf in a tube with more area it takes more air the get the same HZ output. if a maf reads 500hz at 500KG/HR in a tube with an area of 4in sq and you put it in a tube with 8in sq area it will take 1000KG/HR to get an output of 500HZ. The computer still thinks there is only 500KG/hr there.This is an excellent question as some of us would like to initially purchase and install the intake sans tune and then upgrade to a tune later.
The other scenario is to purchase this intake and a tune simultaneously - but then which scenario would make more power - the stock tuned MAF with an aftermarket tune or the MAF adjusted for a tune which then has to account for the newly scaled MAF sensor?
These kits don't need a flash because of improved airflow they need a flash because the computer thinks the wrong amount of air is going in the engine.
You can still tune with our maf, you just need to select "stock intake" in the tune.
This is why I hate the use of these inserts "restrictions" in the maf housing. They are necking the tube back down to the stock size of the maf to get the car to run.
