That's right where mine is, and I'm very happy with it. I've had my cruise close to 16 and would always get a slight miss every 10-seconds or so. At 15, I have a little room and it runs purr-fect... The other issue with being close to 16 was that if a cold front or high pressure system set in [in other words: nice take out the porsche weather], my car would all of a sudden run too lean. So, at 15, when those fronts come in, it might jump up to 15.3 at cruise [and no miss-es].
