Your NA number is really good. Was that with the headers and a tune?
My car was about 30 hp lower NA so I'll probably never see numbers as high as yours with the TS2.
What gear. Are you using for your pulls?
It's interesting see where your DISA was opening on the NA run. Since the whole manifold is pulled with the TS2, there is no drop at all. This seems to support my theory that the 4K dip is just the DISA opening and disrupting the manifold volume and flow for a split second
