I'm not picking on you man, and I'm sorry if it comes across that way.
My car normally starts dumping power at 5500 rpm. When I was running the stock cam at 2 advanced from dot to dot I think about 5200 rpm and the power was gone. I didn't dyno it, but I could tell the car pulled a little harder on the bottom end.
With where you have the cam now what rpm range do you get to before it starts dumping power?
