Good day, I’m looking for an affordable tuner that offers a kit that can bring the 500Ps SL55 to more power. I’m thinking of an increase in performance of around 80 to 100 hp. I don’t want to make any changes to the drivetrain. I would like to ask a few questions: 1. Does the increase in performance work with a pure chip tuning that the “Wastegate” will open later or does another loader wheel have to be installed? 2. Is there a loader wheel for the 55 compressor motor in the trade? 3. Does the control unit have to be adapted absolutely necessary? Or does this automatically adjust in this area via Lamda 1? Thank you Andreas
