Default My old setup with just cone and chip hit max boost at 3950 to 4000. Haven't datalogged lately
But the peak "late" boost is purely ECU driven (not mechanical as in CFM output and exhaust energy), as the N75 D/C was slowly rising to about 80% on this peak RPM and then modulates back down about 700 RPM later.

I suspect that folks using Swing's boost machine peak 500-800 RPM sooner
