I would seriously get a tune...when I put my cam in it threw the same codes till I went and got it tuned the next day but I had that already set up to tune it and babied it home till I got it tuned....
You will never see the true power you can get unless you get it tuned...in my mind its throwing money away if you install a cam and dont get a tune.
