Are you throwing codes or are you hearing an air leak? If it's an air leak, do you hear it at idle or while wide open throttle or letting off the throttle? How long have you noticed the leak?

Smoke!!! Smoke!!!! Are you Smoking yet?

Well I don't heafr it but I was told that because it seems like its lagging bad and it takes longer for the turbo to spool and when I punch it all kinds of black smoke just comes out and no engine light has came on yet soi dunno what to do and it has been going on for about a month now
