fuel problems?

[themeanest240]

i just got my enthalpy tuned ecu today.all its tuned for or should be tuned for is, 550 inj, z32, gt2871.the car ran absolutly perfect before i sent the ecu to scott.i put the ecu in today with stock turbo on and the injectors in.started it and right away it sounded like a subaru. you know the distinctive sound sti's have. my sr sounded exactly like it. wot my wideband reads nothing but lean!!i dont have a fpr to check the fuel pres, im ordering one as soon as i can.also the idle just goes crazy and after warms up its chokes and sits at 400-500 rpm wanting to die,i thought it was misfiring so i bought brand new plugs. same exact s***.the only thing left to be the culprit i think would be the fuel maps, or pressure.someone with more knowledge Please hlep me! thANKS
