Strange noises after fmic install

[bigsprm83]

So I installed my ebay fmic the other day and as soon as i was done, the car made a siren type sound when minor throttle and a train horn type sound as i got on it more. Now when I drive, I feel a huge loss in power and it almost sounds like a subaru flat four. By the way I have the diy intake, and a forge splitter. I've double checked all of my hoses in the i.c. piping for leaks. Could this be a bad turbo?

did you check the lines to the Forge Splitter?

subaru sound = a coilpack failure 90% of the time. (plus a huge loss in power)

also check the boost sensor on the the throttle body side.. make sure u put some type of good sealent on the screwes and that area.
