What A/R hotside do you have? (.64, .80, .85)
What are your basic engine modifications (stock displacement, stroker, stock heads, fully built heads)
What is your turbo manifold design? (bottom mount ram horn, top mount, log, tubular side mount)
What RPM is your boost threshold? (RPM when you reach positive manifold pressure)
What RPM do you hit target boost, and what is your target boost?
Thank you so much,
Marcello

I have the .64 I believe. The OG one.
High 400s and 35psi is what you want? If you're after the genuine "Stomp the gas, **** the pants" experience, I'd recommend to skip the 6x58 turbos and go straight to a twin scroll 7163. It should spool as fast if not faster than single scroll 6758.
Twin scroll is only available in T4 flange, but it's a small price to pay for the exercise your sphincter will do every time you drive.
my spool data is here, btw

25psi @ 3500 rpm

"sensor01" is turbine speed sensor.
