If it's truly on a 110.5° ICL, that could be the reason why it's fussy and harder to tune. Most of the off the shelf cams are either on a 112 or 110 LSA and to install them straight up or retarded is almost a shot in the foot for a street car.

The cam is also mismatched to the intake. If you wanted to get the best bang for the buck, you may look into swapping the intake to match the cam, or swapping the cam to match the intake.
