SC 330 compound boost build Twinscrew/T72 turbo

I am currently rebuilding my engine for a compound boost set up. I made this decision after damaging my supercharger by running meth and nitrous!!!!! Huge no-no. The water froze and pretty much acted like stones in the supercharger, deep scratches and funny noises followed.

So in my quest for more go fast I decided to rebuild something insane, so here we go...

Whats done/what I have...

M30B54 ported head
Cosmetic mls head gasket (lower compression)
ARP studs
Custom camshaft (260/268)
ESS twinscrew supercharger 1.6
Custom 88mm throttle body
Custom intake
Okada plasma lift (on back order)
Ceramic header and heat wrapped
Custom pulley
800cc Bosch injectors
255 lph fuel pump
Fuel regulator
Secondary air delete
Nx express nitrous (75hp)
Nx express methanol kit stage 2

ZHP 6 speed conversion
4.10 LSD
ZHP short shifter

And lots of other parts not directly related, gauges, etc..

I am ordering a T72 turbo for a rear mount set up. I will be running 8 psi on th SC and 9 psi on the turbo. My concern is the tuning and any equipment that would make my life easier.

PLEASE UNDERSTAND...I am looking for positive feed back of known issues and experiences, or known related issues of the build. I say that to say I'm not interested in how stupid the build is....thanks. All comments are appreciated.
Started ESS...ended CUSTOM!
