It varies per individual cases
OK, I have no idea what you're talking about now. This whole thread is about the S55 engine in the M2C. Who brought N55 engines into the discussion?

Let's start again. I asked about the difference between stage 1 and 2 (for the M2C, obviously), and Reid pointed out that for stage 2, DP's are recommended, which has always been my understanding as well as how tuners universally label their stages also.

Then you replied to him that stock DP's are also fine for stage 2 maps, which was news to me, so I asked where you got your info from.

Why don't you share a source / link regarding that?
