What altitude?Lbs of boost? For 6 lbs I have it dialed on the safe side green 1.5 yellow 2.5 red 3 green/blue 5.5 and red/blue 3.5 fuel pressure is at 33-34 lbs, this is on a Cutler stage 2 kit. afr is 11.6 on a long pull with 1100 on my egts. I would recommend starting at 38 lbs fuel pressure and max on your gb and red, you can always pull fuel. These settings are for an altitude of 3000'-7000'. This is all on a 09 M-6 Cheers Jeff
