I just got my DME flashed back to stock, and I will drive it stock through thanksgiving and then I plan to take it in and ask WTF?? I'm thinking they were bad parts from the get-go OR there was an install error.( I actually went back the day after because the car seemed to oscilate- not accelerate smoothly as I left the dealer- they said it was fine) I was afraid that after going back to stock they would quiet down some and then the dealer would tell me nothing is wrong.
Happily, the car is now 100% OEM and still sound the same. Combine the sound with boost issues and random limp modes i've been getting....we'll see if the third time is a charm
I will keep the car stock until spring so that if this next set is messed up- I won't have to go through this ordeal AGAIN.
Install error could cause it, ie, not getting the intake tubes on right and getting something sucked in there. Don't get me wrong I have seen turbos go a LONG time when howling, and I have seen some fail quickly after the noise began. Its not a reason to panic, just know turbos are not supposed to sound like that. Once you start seeing the smoke you know its time to get them swapped. How long that will take is impossible to tell.
