I agree 100000%.... The Crossfire is my first crack at a S/C car. I have had 2 previous modified turbo cars and rising rate fuel pressure is a must in high boost applications. I have asked the question if the stock fuel pressure system is 1:1 rising rate and it looks like you have finally given me an answer. The great thing about our fuel system is that there is a test port at the end of the rail, a perfect place to add rising rate regulator and reroute fuel return. Or inline before the rail for that matter as well.
