This was with an EFR 7163 twin scroll.
The N1 cams are similar to a stock F20C/F22C cam profile (S2000), and those things love boost too.
Honestly, with the N1s, you need a pretty big turbo. A 7163 is the smallest I'd go with. In the EFR world, I wondered what a 7670 would do. Probably still pretty strong response and even more nuts top end. That said, even the 7163 made so much power it was getting a little hard to manage at ~18 psi+(1.2 bar+).
The sound on the big cam is worth the N1s alone.

I have custom cams very similar profile to the n1 and an efr7670 going on mine , will post up the results when it’s mapped in the new year [emoji1360] hopefully should still be pretty responsive
