Need help with Z32 maf in a S14 KA-T, please!

[Turbo Nismo]

Hi, I installed a 300zx Z32 maf in my nissan S14 KA-T, with 95 stock ECU and a safc II. I put the cables just like the Z32 installation diagram says, Like this:



And out putted the safc II in in 2 and out in 5, the car starts, and runs fine in low throtel but when I try to boost him in high throtel it rev's in 4 000 rpms and it only boost's like 2 - 3 psi and it wont go further, but in low throtel I can go to 6 500 rpms without problems. What could it be? Do I need to put something else in the safc II to make it work?

My set ups are :- 370cc sr injectors-Z32 maf-Safc II-Garett T3/T4-ARP head studs-Cometic Gasket-Forged Eagle rods-Nippon pistons ( Not forged)-Walbro fuel pump-38mm ebay waste gate-Ebay turbo manifold-FMIC-Malpassi fuel pressure regulator 1.1

And I'm running @ low boost 6-8 psi

I need help please!Thanks.

make sure you dont have any boost leak. what's your vac reading at? usually bad maf wont let you rev to a certain point. i need to double check your diagram for maf wiring. also your afc 2in 5out is right.

EDIt: how far is your maf from your turbo? should be at least 12inches. unless if you're running blow through.
