Recently installed Flowmaster 70, should I disconnect battery to reset PCM?

Hi all,

Thanks for the advice on my mods. I really like the 70 series. Not to loud, but defiantely improved performance (acceleration wise). However, mileage is either the same or slightly worse. I was expecting it would be slighty better though (maybe I am heavier on the foot now with my new sound).

Was wondering if resetting the PCM by disconnecting the battery for a few minutes would help. And if so, how long do I need to leave the battery disconnected (I assume the PCM has a backup battery for when the main battery is changed).
