When I step on full throttle, or get up to speed at had throttle and then try and punch it, as soon as it starts making boost it backfires and stalls out. I checked all vacume lines, everything is fine, so I'm thinking fuel injectors aren't spraying enough at full power?

most likely spark plugs are fouled or not gapped properly.

I'm having this same problem! Would you just take out the spark plugs and see if they are fouled out? Would it be best to just buy new plugs?

Alright I fixed mine, turned out to be the person before I bought the car was messing with tuning. I bought a Diablo intune tuner, put a new tune in the computer and it's 100% fixed!

I fixed it with a new tune after having bought new fuel pump, bench tested the injectors myself, new high perf coil, wires, plugs, played with gaps, etc. Turned out to be the computer itself.

at least you figured it out and all those parts you replaced are wear parts anyways.
