Seeking R231 SL63 ECU Tune owners feedback
Greetings All - I recently purchased a MY17 SL63 ... and am considering an ECU tune ... what I am very interested to hear from those that have had the ECU tune is the Daily Driveability Characteristics .. specifically, did you notice a degradation in the daily driving in terms of smooth acceleration / deceleration & shifts ... while I am sure several companies will deliver on the increased hp and torque, I am concerned if the amazing "normal" drivability I enjoy today will be sacrificed. Thanks in advance for your input. Steve

Porsche guy who drives SL63 w/ perf pkg AND perf suspension
I would call renntech and discuss the characteristics they describe , since they get feedback and have their own experience with the tunes they develop. personally, with other cars, a tune makes the car feel more responsive
