new turbo installation

[wired1]

I have recently installed a new Limit TA-49, new waste gate actuator, new 42lb injectors, adjustable fuel pressure regulator, and new HP fuel pump kit w/hot wire, have K&N set up, and 3" exaust, just replaced the radiator because last owner was cold and installed a brand new custom fit piece of cardboard in front of the radiator! I think the overheating is what fried the last turbo. I did adjust the new actuator to the same setting as the old one, not that it was right(according to the cardboard). Anyway, just took it for a ride and it is popping like crazy and hardly built any boost at all. Brought it home, let it idle and parked it and the turbo was super hot. Any suggestions?
