Don't have any info on that, but Dave(2005HHRauto) has done a lot of testing with different DP configurations. Here's his thread https://www.chevyhhr.net/forums/hhr-...t-power-43170/

If you are doing it as a stand alone mode, i doubt you will feel any power difference. I think it is more of a supporting mode, if you are getting tuned or going bigger turbo.

None - the stock tune in the SS has a learn down feature. You would need to go to some aftermarket tune to defeat that feature. Even GM's own upgrade defeats it.

You probably won't see much unless you do some major mods that increase exhaust flow.
Otherwise I would assume you would lose some low end power and gain a little top end if it's even noticeable.
