Ok guys. Cars a 2016 pp 5.0 m6. Having issues with a strange noise I'm hearing. When the car was bone stock I did not hear it at all. As soon as I installed jlt, tune I heard it for the first time. Care is tuned by aed. Can't say enough about Shaun trying to help me with this issue. It's not anything to do with his tunes or anything he has done. Now on to the issue. When you all of a sudden go wot you hear some sort of click or knock coming from the engine. Say I do a 20 roll and go wot fast as shit it does it for a split second pulls up to 6* of timing and will do it everytime I shift or the throttle is open closed really fast. I can put the car in neutral I can rev fast and hear it. If I roll into it it will not do this at all. I've been searching and searching for shit it could be and can not find anything. So I put the car back to completely stock and it will do it but not nearly as much as it does with cai,tune. I can barely get it to do it stock. I'm planning on going to the dealer but I feel I'm going to have a hard time showing them that there is an issue. Can't exactly show them data logs showing it pulling timing and such. Has anyone had this sort of issue?
