Truth or Consequences
ORIGINAL: gunrunner
Well this may be true on the 06, but the ECM on the 07 is not the same it is now a limited closed loop system and it will compensate for exhaust, now thats what my dealer/manager told me, so I guess we dont know any more now than we did, except I believe my guy, and know a closed loop system can self adjust somewhat to changes, notice the other stated air cleaner too, but the original question was mufflers only. Add a SE air cleaner and yes you will have to go beyond the stock ecm.
