PCM reset ???

[hawk02]

Do I need to disconnect the - battery terminal for a bit after my catless mids install?? I noticed my overhead console now reads 5.1mpg vs. 13.2 before the install or do I just need to drive it so it can "relearn" the new flow, only driven it 20 miles or so since the install........ Thanks... My old Hemi truck did this every time an intake or exhaust mod was done.

Definitely....pull both pos/neg terminals and tough together for at 15 seconds. Then reconnect and enjoy. :rock:

Is that the best way or is there a fuse I should pull?
