Isn't that the goal of every dsmer? Or is it 650?Unless youre making 600+ hp, SD is useless.
No, the goal is to not break down....as alwaysIsn't that the goal of every dsmer? Or is it 650?
Your points and end result contradict each other. In what cases would you want to have a boost leak? In what case would you want a sharp angle in air flow? And why would you put a band-aid on them by switching to SD?
Also, the amount of power you would lose below the threshold I spoke about is so little that you would not even notice.
When I was on SD and decided to switch back to MAF i recorded the airflow. The differences were so minimal I never looked back. Differences were below 50 hz
This was at roughly 500hp.

I'm specifically talking about GM MAFs. GM MAFs being garbage is more my opinion based on my experience with them, rather than fact, I suppose. It's the tuner who makes the power, not necessarily the equipment in this case. If a MAF, or GM MAF is what you're most comfortable with, then I'd say stick with it. As such, my car runs all around better on SD than it ever did on a MAF, so I prefer it.
I say handicap because GM MAFs are notorious for being garbage on DSMs. That especially holds true when interfaced with ECMlink for some reason. Personally, I've never seen a single GM MAF car that had a consistent all around (idle, cruise, WOT) tune. Not one. Maybe Bastard's car is the exception I've yet to see? Even so, good luck to the average Joe doing whatever the hell he had to do to get the thing to run like stock, which I assure you wasn't tweak the MAFcomp table in ECMlink. Dude wrote his own tune/code for god's sake...
Considering that, I think they are a handicap when compared to the many cars I've seen and tuned on extremely consistent SD setups, or even other MAF setups (like the Evo 8 MAF, for example).
Lastly, there's no power threshold where SD makes more or less sense, IMO. The tune and tech are tailored for the build, and to the builders preference. When the tech limits the consistency of the tune, that's where you'll run into problems. If you're BastardDSM coding your own tune from scratch, it doesn't really matter what MAF is on the car. But, if you're the average DSM guy asking for 3rd gear pull advice on a GM MAF setup, I'll personally tell you to ditch that junk every time.
For all out performance I never said it wasnt true. So I would like to thank you for putting words in my mouth. Makes. you. look. even. smarter....
Also, I would not consider a DSM at 500hp "all out performance". Maybe you do because thats all you can make? Who knows.

Oh.. I'm so sorry @bkrathwohl that this has turned into this but I've got to point a few things out.
This is what I was pointing out, all opinion based. Some other people with ego problems look past this.Brett said.. very simply. that this was his opinion. multiple times.
