That a1000 isn't going to keep up if you're running high base pressure. Got a built 331 stang in the shop that we put a gt4788 on 35 psi base pressure 13 psi of boost made 650 on our mustang dyno and was out of pump. Fuel pressure was all over the place at the higher levels. Customer bought a Weldon pump. The car went on to make 750ish on pump gas and 1024 on c16.

I'd upgrade pump if it's possible

When my truck made a lil over 425 it started to suck the rails dry. Could have been injector or a mix.

aeromotive specs their a1000 at 600lbs/hr at 45PSI, capable of 1000 crank HP.
Next step up is a magnafuel 4301 or 4101

speed inc makes a rail kit that should work, give em a call
small motor, single plane, turbo.
