wtf? did my car somehow loose its tune?! Well this is all a week after my car got tuned on the dyno....
I was driving down the road and i saw my SES light come on (i was near autozone) so i had em check it out... They told me that i threw codes
P0405 (egr voltage is low)
P0140 (insufficient activity from o2 2 in bank 1)
P0160 (insufficient activity from o2 2 in bank 2)
P0300 (some missfire bs)
heres the thing... when i got my car tuned i had him turn all the egr and the rear o2s off
WTF happend to my 400$ tune! why is this **** showing an ses light
also... could p0300 and the o2s be related? If not what could be the problem? is My Air fuel messed up?

you must cut them off in the DTCs and the MIL status

my tuner said he did both of those... any other suggestions?

Think there is any kind of relay or anything that would have caused this?

As mentioned, bring it back to the tuner and have them re-set everything for you. I'm sure he might have said that he disabled the EGR entirely, but he must have overlooked something...

cars don't just lose their tunes. print out the whole thing i posted above and take it to him and have him turn all that off, well if you want. Otherwise turn the EGR off

Check all your plug connections on your entire wiring harness. Mine was throwing alot of codes also. I went through and found a couple of plugs that were not snapped on all the way. When I did this all of the codes magically disappeared...
