Re: starts breaking up at 4500 rpm.
Are you changing pump setups between the 2 systems? Your pump my not be putting out enough flow at the higher pressure 40 and above, but put enough flow at 7 psi for a carb. I have run as fast as 11.60 with all the stock fuel lines in my car with just one size up pump. This is also a 5.0 mustang.
