Just returned home.
Engine no longer dies but still has small oscillations that cause surges when at a light. No in cabin smell, sound is not annoying and when you throttle up it sounds pro style. Power (untuned) is a really nice bump, shift point between 1st and 2nd makes you smile (at least it made me smile) and continues to pull like a tractor all the way up to shift. Tuner is looking at 25-30 more on the dyno. He is also fairly confident he can tune out most of the issues - idle, revs etc. but the S2 cams also effect the 56 motors in a similar fashion.
