I did the search, and still don't know the answer. If you put on a BAK, do you have to block the AIS too, or is it blocked by the installation of the BAK? Is blocking the AIS a personal preference, or does it increase performance? Do I need another kit, or does it come with the BAK (I'm getting the V-BAK). If I'm going to put the BAK on, does it make sense to wait and do both at once? Will I have to change settings again? Or can I leave the AIS alone, and just do the BAK with good results?
