Ok i got a motor built

Everything was done that could be possibly done.

When i start the car up , it idles fine , i give it gas the RPM`s go up without a problems. NOW....When i go to drive it in 1st gear when the motor is just about to make boost , and is underload , the motor sputters , breaks up and shoots black smoke out of the exhaust like it is its buisness!!! . NOW i have a 02dump and when i undo the wastegate on the turbo and the car makes no boost , the car runs fine :nodno:

Someone tell me what it could be

You sure it's black (running rich) and not blue (burning oil)? Check for boost leaks first.

i think its boost leak check all intercooler connections, Run a leak test. Could be spark plugs maybe? Check those things out first

you did remember to plug in your mass air sensor right?? sounds like that or one of your I C pipes are leaking make sure you tightened them down cause when you go into boost if one is left loose it will blow right off, Also could be ECU, Thats what my Talon did before the ECU took a shit, it just got worse and worse till it wouldnt run anymore
