brand new platinum cured silicon lines, replaced those 2 weeks maybe 3, even went as far as zip tieing EACH connection...I triple checked all the lines last night including the ones under intake manifold, everything is in its place.. Anyways all was well till about Friday or Saturday night, which is when i noticed no power down low... Ended up replacing the blow by pipe from tunemyeuro, intake air to exhaust seal, new boost pressure senor and seal, cbu cleaning 3 weeks ago, all new gaskets on manifold, (the list is extensive,) in hopes my issue would be resolved but no dice.

Regardless i have no CEL for anything other than 4bcc, which is have new 10k ohm resistors in route. MY paid version of bimmer tool doesnt seem to show correct boost readings either ( always showing around 25psi even when off throttle. Ive seen Andrews videos on testing vacuum and actuators but seems like one would have CEL in that situation or am i wrong? Only other thing worth mentioning is my air mass readings on the app are showing 500s and it says it should be around 2000? Also back pressure test is showing single digits numbers ?
