I understand what your saying, however when you program for the proper tire size, this fixes that issue that your explaining. I can bet that if you were to pull the AEV module and correct the tire size with some other means of tuning that you wouldnt have that issue anymore. So again, does the module really do anything besides correct the tire size to fix the problem. I think im going to call AEV tomorrow and have them explain to me exactly what it does.
