I can't believe after he admits a coupler is loose and he hasnt done a boost leak test people are suggesting other things.. Also just cause your boost controller is turned down doesn't mean your not running any boost. Can't expect your car to run good if it thinks its getting a lot more air then what it's actually getting. Do a boost leak test and go from there.
