The "tuning" refers to the diameter of the area where the MAF sensor slots into the intake. They keep the diameter the same as stock in order to keep the A/F as close to stock as possible. I know that other companies do this as well. Such as Airaid for other cars (which is a company that uses a removable insert so that you can open it up once you have ecu tuning available).
If you look, the diameter necks down around the MAF sensor. That is the "tuning" they speak of.
