Finally got to put my De Cat header on Saturday along with the FL-XIED -10. Today I drove it for about 50 miles and noticed a lot of deceleration popping.Im running the stock A/C with screaming eagle street cannon slip on's . Should I adjust the FL -XIED I assumed it came pre set cause the asked me when I ordered it what I was running . I believe it is set at 50/50 does anyone have experience with these and what settings are you using. Thanks in advance for your help
