Ive heard when you put heads or a different cam that the engine idles really bad because of the computer on it. Would the same thing happend if i threw a supercharger on it too? And which would you guys reccommend either a powerdyne or a procharger? I was thinking the powerdyne since it is belt driven and quieter but, would it be as good performance wise. I was thinking from 6-9psi for the boost. What would be the best for my application?
