I guess it depends on your set up I think. If stock lines with a walboro and 1600's is dropping off at 40 lbs/min, I would try a bigger pump. Then lines next. 1600's have gone allot farther than 400 whp with E, but they had bigger fuel supply. That tells me that the injectors are not getting the fuel that they are capable of supplying.
