Help! What could cause this?

Well im having a hard time trying to find my problem. I made one run on a dyno test. On the dyno sheet there are gaps between the hp lines, and i only ran 305rwhp. The power seems to just skip or something. The car is running rich and hesitates at low rpm. When i floor it, it seems like it has a loss of power, but dosent hesitate or jump any. What are all the posibility's of this? I was thinking maybe distributor cap, wires, or spark plugs. The rotor and sensor on the distributor are brand new so i dont think it could be that. The wires and plugs are also almost brand new but it is still a posibility. The car is not throwing any weird codes. My crank position sensor is deleted so i dont know if it is misfiring or not. I can send pictures of the dyno sheet if that would help any, just email me at ace2813@hotmail.com. Anyone that can help would be appreciated.

Make sure your plugs are gapped correctly. Thats what I would try first.

sent you mail

I sent you mail seal, hope that helps some. I dont think it would be the spark plug gaps, they are brand new spark plugs and i checked all the gaps when i put them in.
