Looking at adding a piggyback system to my car and have a few questions
1. Do both systems work in the same way
2. Is jb4 stage 1 simple to fit. Does this give various maps and are they controlled inside the car, I understand that tmc is controlled by a button on the device
3. Has anyone had any issues with these systems
What is the best device ie value for money v performance gain
Not looking to use on a track
