Golf R here so I don't know if you care about me or not. I added the JB1 only (hardware stock) on the stock +4.8 map. I started slipping after about a month of use. I didn't really abuse the car. I'm 45 and am not clutch dumper, etc. But rolling into the throttle in 5th and 6th slips the clutch. I moved to map 6 and the clutch no longer slips. Then, I took the JB1 out for the 10k mile service (so the dealer wouldn't see it) and I honestly can't tell the difference between stock and Map 6. I may just leave it stock and use my stock clutch as long as possible.
