fuel regulator was fine, relay fuses to the double pumper were checked, boost leak was good, cam sensor was switched. what else can it be??? anybody who had the same problem on their evo get it fixed???? around 4k rpms its getting 2lbs of boost and its running lean..... oh and the wastegate was checked its fine as well
