When MAFs attack they usually cause pinging. It can sound like your engine has swallowed some marbles. 2001 and 2002 were the years of bad MAFs. The airflow in to the intake is also calculated by the speed density system using the MAP sensor, IAT sensor and RPMs. The MAF is just for fine tuning.
I would not hesitate to contact Chad, however there have been several posts about having them rebuilt or even taking them apart and cleaning the sensors in the throttle. If it gets worse it will go in to limp home mode. You can put it in to limp mode by unplugging the 10 pin connector at the throttle and then turning the ignition on. You will hear 5 loud click clacks from the throttle as the limp home solenoid kicks. I f you do that, then you have to disconnect the battery and reset the throttle. There are also dozens of posts on that.
A throttle does not have to be programmed, but you do have to disconnect the battery to clear the codes before installing a new one IF it is in limp home mode and the CEL is on.
