thanks for your reply i will update you on the mods on the car i am running at 10psi off boost at the moment we have a massive intercooler boost controller, fuel cut off and i received today the low resistance direct replacement 550 injectors and i am waiting for the fuel pump. we are planning on putting the sp61gt turbo and i also have the lexus afm body ready to fit. planning on taking it up to about 500 bhp with the lexus afm body and the 550 injectors and bigger fuel pump. will the car be over fuelling. because i have been told that with this set up it will be a perfect match. but i have also been told that it will over fuel. apprantaley with this set up its suppose too trick the computer so the fuel and air flow will be a good match but i am not sure of this. be great full if someone could give me the information i am looking for before i start.
