So it will offset the increase in boost somewhat. I don't like how people keep talking about, "oh just retard the timing!" As I remember, he was running only 8 degrees of timing when he put down around 380 with 19 psi of boost. Well, if he was running 15 degrees, there's now way he could run 19 psi and not get detonation some of the time (can't always hear it)...unless he had an AFC. Let's also remember, this does not happen for the majority of Z's. So advising people to do it is not a smart thing. I hope this makes sense because there are very dumb things being said about this whole matter.
