Um, when you install a camshaft(s) with more lift and duration, you make the engine run less efficently at lower rpms. Hence your rough idle. If you would have checked with the manufacturer of your product you would been told that idle quality usually goes in the toilet when using a more radical camshaft. Fuel pressure wouldn't have any play with that.
