Mafs?????

[HATChTRICK]

Ok here's the deal.
95 240
S14 sr20det

Full race turbo with t3/t61
Greedy intake manifold.
Dwerk's 660cc injectors
Z32 mafs
3" turbo back exhaust
Waldo fuel pump
Pulley kit
RS Enthalapy rom tune ecu

That's about the just of the main components.
Car will start and stall within 5 seconds .
Unplug Mafs and it idles perfect but won't rev past 2000-2500 then starts backfiring. Plug mafs back in and car dies right away and will not idle. I have NO vacumn leaks. With mafs unplugged vacumn is 19-20 psi.
All my grounds and hooked up.
Mafs is wired correctly ( checked it 3 times).

Does anybody have any ideas?

Sounds like you rather don't really have a z32 maf, your z32 maf is bad, or you're tune isn't really for a z32 maf.
