Mine runs great (it starts, idles, runs down the road) but I have no idea if it's running lean or rich. I'll plug it in tomorrow and see where I'm at and then start making adjustments. Gregski's tutorial doesn't address tuning for a cam swap and I'm not sure if he's planning on it or not. The only reason I got a mail order tune is because of the cam swap, otherwise the basic swap changes would have been fine (delete VATS, rear O2's, cats, etc.). At this point I'm considering the mail order tune a base tune and as long as there's nothing catastrophic that leads me to put a stock tune back in and start over, I'll use it as a starting point.
