TCU tune? Worth it?
I wanted to get your thoughts on getting a tcu tune for my 2016 E63. Is this a no brainer? Worth the money? Hold off?
I currently have a Weistec ECU tune and a BlackBoost intake. I was considering on getting the Weistec tcu tune so I am hoping for some insight. Any input would be greatly appreciated.
Thank you,

these cars weigh 2 tons, and have enough tire under them they don’t slip the rubber, especially the S cars with the limited slip. That’s hard on the drivetrain when you start upping the power.
