Hi recently put a turbo in my lexus is200, Td05 full set up with fuel regulator, upgraded fuel pump with return line, 1zz injectors, sump etc. car was fuel cutting every time hitting boost (.5 boost). Tried 4 different fuel cut defenders and piggy back ecu and nothing worked. Changed all spark plugs, coil packs, throttle body, ecu everything and still fuel cutting. I also put standard injectors and fuel pump back in and still fuel cutting. Anyone able to help me out? When disconnect the pipe from throttle body and run car without turbo its perfect but when connect pipe back up issue starts again. Thanks
