Exhaust pressure sensor check engine light

Help me out guys i have a 2012 with rear muffler deletes and the stock exhaust valves modified so they stay open. The check engine light came on took it to dealer they said it was because i had the valves tied open. So they put the valves back to normal and then i opened them at home again by moving the spring so they stay open instead ofclosed. Been driving around like this for 4000 miles not one problem and today the code came on again. So anoyyed with this crap i just want to enjoy my exhaust and not deal with this crap. Can anyone help?

Code is p0471

Youll have to get a tune to avoid that

Re: Exhaust pressure sensor check engine light

like scott said, get a tune, disconnect negative terminal from battery, or just ignore it. it will go away after a couple start stop driving cycles with a light foot
