You need to watch what you say on here. I see you're new here, but you need to know you can't say things like "when doing a 120mph highway pull" and "if you need more info hit me up on this forum" That's a good way to get nowhere fast. The time is now to get you problems solved, but you have to help us help you by being more specific about things like how and when it does this, and how it feels etc. Have you done basic maint.? So, I think I've said enough. Now you need to tell us more.
