With it being a procharger instead of a ddm or alpha(only ones that offer Superchargers for the sling) makes it a definite pass, I have only heard of two people in the forums getting the procharger and both ran poorly and had a lot of problems.
Now both could be due to human error on the installer part , I know that procharger makes great products used all over muscle cars and what not but the fact remains that at least in our little corner not many are using it and those that tried things didn't go well.
