Well there is a considerable difference in the mid-range torque between a Speedie and most everything else in the same displacement class, so if your buddy wasn't running that Kawi in the top 25% of his rev range he's at a considerable disadvantage.
I think I'd have been worried more about the 'origins' of the bike at that price with those miles.
FWIW, my '03 955i will only keep the front wheel on the ground in 1st if I lean as far forward as I can - even then it's an inch or two up until I'm out of 2nd gear (at about 90).
Celebrate the performance lad, and welcome to the zoo.
oh, and btw, don't be afraid of TuneECU. Buy a cable (around twenty bucks; but READ the TuneECU thread before you buy!), download the app, and bond with your Speedie.
