Have a friend with a 2016 Z06 and he wants to if there is something he can do about the throttle hanging. I've never driven the car so I can only go by his description. He says that when he lets off the throttle that the rpm's hang for about a second before dropping as if the throttle blade isn't closing. Is there something that can be changed in the tune to eliminate this?
I can post the tune if necessary but it's completely stock at the moment.
Thanks!
