Thanks for all of the replies! It definitely looks like I have some homework to do. Who makes "n gauge" and how many tunes will it come with, and what kind of pricing will we be looking at?
What is the best tuner to go with? 2015 5.0 GT Automatic, JLT cold air kit(not installed yet), Driveshaft Shop 1 piece aluminum driveshaft, Gibson cat back. Thanks in advance for any help!
Well instead of taking back to the dealer, I went ahead and ordered a Driveshaft Shop one piece aluminum driveshaft. I will post the results once installed.
Well a Technician and myself went for a ride and he definitely felt the vibration. First thing he thought was that a tire/tires were out of balance, that's when I showed him this thread. He said that he was not against putting a new driveshaft in the car, but would need for me to bring the car...
I've been having the exact same problem with my 5.0 automatic since day one...500 miles now. Thanks for posting! I have an appointment tomorrow at my dealership and will show them this thread!
