Cam just installed
As far as getting on it without the tune (most of us did the same thing) however it is not a good idea. I hit mine a few times here and there and 1 time pretty hard on the way to the dyno. After making the first pull I thought to myself man that was dumb. The a/f was around 14 across the board and at 58 it spiked and went wayyy lean! Granted it was not the stock tune for I had a friend throw in a canned tune to get me to the dyno. Just my .02
