I know there’s a few threads here and there with this mentioned but wondered if anyone has actually gone for it? I had the drive ability map done on my last RS3 as it was running stage 1 Apr. That helped with change points and eliminated that horrible bang on gear change 1st to 2nd at 5k rpm in manual. Since having Revo stage 1 on my R I’m in the same position, I can get a similar rough change 1st to 2nd in manual. Anyone that has it have you gone for the drive ability map or stage 2+ Pros and cons please. Also heard it mentioned it could be done at home by a diy dongle to save the 100 mile each way travelling.
