Hi Viv
You can simply disable the AIS by removing the vacuum pipe from #4 intake stub as you've done. Your popping was a combination of the AIS activating and the wide-bore can, which tends to make any popping of this kind sound more obvious.
Removing the AIS improves access to the top of the motor for plug changes etc but otherwise has no effect on performance. A good time to do the permanent removal is when you check the valve clearances because the AIS has to be removed to get the cam cover off.
Glad you've got it sorted for now.
