Just got my tm7 up and running and went for first test and tune. I am running BD ADA box and the rest is a hodgepodge of parts. The question I have is this, the turbo I bought had a 14 psi actuator and being a tightwad I tore it apart and changed the spring to a very light hardware store variety. I am getting 4 to 9 pounds of boost depending on where I set my manual controller but it seems that the wastegate is opening too radically and dumping too much boost pressure causing the sled to stumble. Anyone out there ever run into anything like this?
