Hello everyone i recently swapped out my motor for a new one I upgraded to nismo 615 cc injectors and have a jwt ecu which I did pull the EPROM and sent it out for a retune . For the correct fuel maps. I did the swap myself idk if I messed up anything major but the cars just spitting smoke black smoke it's reeks of gasoline running super rich could anyone help me out with some ideas of the problem . I'm positive it's running rich and isn't oil or antifreeze . Thanks for the help guys
