flooding, why?

[mjjstang]

ok well noone really responded to my other thread, maybe it was just too complicated, basically the engine is flooding, I drove it around, backfired and progressively got worse and worse to the point of not starting. s13 redtop, maf is good, just got 600 cc injectors from deatchwerks, which are all working, I tested them, because He sent me a bad one at first which he replaced, so they are all good now. enthalpy tuned, and I know he has a very good record, so im wondering what the hell is going on, any help is good, I am at a dead end and next step is to sell everything off. AND DONT ASK FOR PARTS HERE. IM NOT PARTING IT OUT YET. btw, engine worked fine with stock injectors, stock ecu, z32 maf with safc, and stock turbo, now after upgrade, this shits goin on, so im thinking it has to be something with ecu tune?
