16 SRT Cherokee noise on hard launch...
Ok, drove all weekend to get 500 miles on it so I could launch I once or twice, first time I just nailed it from a dead stop, sounded like a mason jar of bb's in the glove box...it's like a scaping dragging sound, if I use launch control u can hear it before u release the brake? Then it does it pretty much thru first gear, almost sounds like a diverter valve on the exaust or something? Idk? I was a tech for Chevy and Mercedes for years, never heard anything like it before...kinda got me concerned after paying $75,000 for it!!! The very last thing I wanna do (and doubt I would regardless) is take it to the dealer and let them do 125 hard launches in my new jeep...any thoughts would be appreciated.
