I installed some bullseyes on my 05 f7 efi dd last week at the same time I installed a pac system from d&d(I know I shouldn't have done 2 mods at once but was in a rush.
When trying to adjust my pac system I set it backed out the 2.5 turns as instructed and continued turning it out 1/2 turn at a time each run after checking the plugs which every time they were pure white. I turned the pac out untill just before the needle leaks out fuel and they were still white. I taped over the bullseyes as a last step before removing the pac and the plugs were fine. I should also mention it was -26* C that day

This weekend I put on 500 miles with the pac set all the way out and bullseyes covered again the average temp was -26* C

There is another discussion on whether a High Flow Air Tube increases performance. The original question was whether a High Flow Air tube would create a lean condition. It appears from your experience it may. Are you keeping our Bulls Eyes covered all the time or only when the temperature drops considerably?

unfortunately it's been cold here since I installed them I'm hoping to go out this week end and try, it's supposed to get to -5* so it'll be a good test. I wish the plugs were easier to get at but c'est la vie.
I was also considering a d&d y-pipe but I'm scared to now.
