It has been mentioned that the combination of an Edge programmer, A CAI , and the Roush off Road Exhaust may cause a lean condition. Is this only when running on the level 3 canned program ? Or Does that apply to all of the programs? I have Just recieved my off road pipes, and will be Installing them soon. I also use the Roush CAI, and an Edge programmer. Untill I can get it on the dyno I want to play it safe. Any Help?
