Great, I've been pushing 20 +/- psi on the daily and no issues/codes (pending or otherwise) anymore since switching.

My .02 is to only go one step colder if on a tune only (I hit 15psi at most with the JB4 off) but if stacked with tune and JB4 (I'm not assuming that 5+ psi will add another 100hp but I'm adding meth VERY soon), NGK says it's better to be safe than sorry I'm following suit and I went two steps.
