I think 5 or 6 of the total posts on here are helpful to him, the others are just bullshit. Sorry guys. On the other hand, I have owned a turbo'd GSR hatch that was dyno properly and with a wideband o2 sensor to have someone at a local reputable shop here in Tampa tune my V-AFC. After everything was properly tuned like most turbo'd cars, 4G63 or not, it would puff a bit of BLACK smoke out in between WOT shifts. Like I said before, If you're not fouling out plugs and its not smoking all the time, just a puff here and there that you are tuned a little rich which is perfectly alright. Ark, if you have nothing to say thats helpful, PLEASE stay out of the post.

The point Ark and several others are making is you should not take technical advice from someone who lies about thier tuning abilities. You would not invest your money in a company says they are doing well but does not give you a portfolio would you?
