I'm confused what the point of going SD is if you're just going to guess what your charge temp will be based on what IAT you have at the intake. At that point what is the real benefit of running SD over a MAF based setup? The only reason I'd go with a SD tune is for more precision throughout my tune based on more accurate charge temps. I've toyed with the idea but on a daily driven car it seems like much more of a pain in the ass then it's worth. If someone can convince me otherwise please do, I enjoy throwing money at my car lol.
