Performance tuning
Sorry but I'm not technical so I hope I'm asking the right question....
I've read all the posts about tuning vendors, they all seem to say the same thing as far as performance gains.
I have 2 AMG cars with Renntech tunes, they have you send them the processor to tune and I have a Raptor that I programmed from ODB II port. Are there places that do these types of tunes for F90s? All the vendors I see here have boxes you plug in and leave. I don't have experience with plug in and leave boxes.
Can anyone provide their personal experience with the vendors and who they recommend?
