I've been running my JB4 on Map 2 for a little over 1 year, and put on over 40000 kms with no slip whatsoever. With that being said, I have never done any high RPM launches. I also wait until the clutch is full engaged before getting on the gas in my shifts. I don't race, but, I do drive "spiritedly". Interestingly, I also do full gas pushes in high gears, and haven't experienced any issues.
I'll be going with a Stage 1 tune (probably Cobb) in the summer, when my warranty expires (80000km), and will be interested to see how the clutch handles it. If I have to replace it, then it is what it is. I'll leave the stock clutch in, until it gives me grief.
