The problem has been slowly getting wrost what happens is it getting low boost I usually boosts 30psi at 100% pedal position and no it's not throwing a over boost code and setting into a limp mode an now it's only boosting around 22psi at 100% pedal position then it gettig about half the fuel mileage it used to have if the truck is died cold the truck loop will in till it's warm and have about 1/4 of its power it usually has, it doesn't smoke white or blue on start up at all starts up quick but low power till its warm, the oil is super clean just did an oil change rotal 15w40 pulled my turbo off last week and it was clean as a whistle pulled the exhaust back pressure tube and sensor off and both were really clean, pulled an IAT2 sensor and it was super dirty so cleaned it off cleaned my maf and runs a bit better nothing really, tested my FICM and it was at 47v an it's the 7 pin, I have no codes coming up, took it to ford and no codes on there computer and they had no ideal to where they would even start
