Well just the other day i was driving around and i could of swore i might of heard a pop sound but not 100% sure . Well now at around 50-60 it feels rough as hell , and not only that but even feels like a power loss and if u punch it just a little from a launch there is a noise coming from the gauge cluster , almost like something is slipping in the speedo, this never happend before until this happend. Any Thoughts Ideas I would greatly apreciate it. I am probably going to buy a 12 bolt but still would like to know what is going on. Thanks For Time guys..
