I bought my msp used and have never brought it to the dealership. I have a intake and blitz dual tt. I was going to bring it to the dealership to get it flashed and to see if I can get the clunk in the back to stop. I was wondering if you think they will give me a hard time? I havent really ever talked to them so i am not sure how cool they are? Also how do you know if it is a mazdaspeed certified dealership. I live in central PA if anybody lives around here and know. Thanks.
