what would be better for my application. the EPS is form idle to 5500 and the performer RPM is 1500-6500. i have stock heads a 570 cfm carb,a mild cam(dont know the specs) hedders. is the rpm intake compatible with my setup or is the EPS a better one to go with. It seemed to run better with the other intake but wanted more power thats why i put the RPM intake on.
