my sr powered 240sx is out running rampid on ny streets... sadly i blow off some black smoke, i thought i was burning oil but i try other things and testing, finally i smelled the exhaust and realize its kinda a gas smell, i just bought the car from a guy recently and it has 700x injectors and a big greddy intake manifold, on top of a few other things... i guess my question would be, would a greddy e-manage ecu/piggyback fix my problem? also when i bought the car the owner bought it done up the way it is..... im gonna get a pic of the turbo, maybe you guys could tell me if its aftermarket...

ps- im not a noob, this is my 5th 240... and my OG user name is tecca best, i just dont have that email/password anymore

ill post pics in a few... thanks for your time.
