Did you have a tune on it? Are you the orig. owner? Sounds like you lost a tune..

8vetts sorry for the late responce, i do not have a 392 but know they were late to market with it being able to accept a tune. Either way, just sounds like something I would look into. Yes if orig. owner had a tune on it then he likely had a hand held tho mine was a second hand with a tune and I never got the hand held unit. A shop could have added a tune independently I guess also..
