Your observations are consistent with widespread reports related to 
surging. When the owner of a surging R Oilhead pulled the Cat Code Plug 
(CCP), fuel consumption increases. If that's your reason for pulling the 
CCP and mileage is an issue for you, consider getting a Techlusion box 
(www.techlusion.com). It eradicates surging in most cases but increases 
fuel consumption (less than pulling the CCP, though). Another alternative 
for curing surging with a very slight improvement in fuel economy and 
power, is dual plugging, but this is the costliest of solutions (see 
www.sjbmw.com, click on service, for more info).
