Have an MS3 cam with lt headers, off-road y, and hooker catback. It has been running real rich when it gets up to max opperating temp. And it belches out a blueish smoke when its doing this. The guy that tuned my car said that its due to the overlap of the cam and that there isn't a lot he could do about it. Also he tuned the car with ls1 edit. The car is a 2000 SS Camoro with 54000 miles on the motor. It isn't using any oil eather so I assume it is fuel smoke. Any suggestions on if or how we could stop this or if we could lean it out a little. Thanks in advance.
