I have a 6.4 stroked to 7.0. I installed FIC 1000cc injectors and installed the supplied data for the injectors and I have 2 issues. One runs very rich at idle and surges, on the offset table when I put in their data it pulses and sounds like a blown supercharged engine surging big time at idle. The min. pulse rate that came with them is .350 still way to rich so I have brought it down to .150 has helped some but not enough. Any thoughts on this???
