Spun my hub the first time out at LRP with a VF Stage 1 tune. Call it luck of the draw but it failed within 800 miles of getting the tune installed. I believe the heavy torque the tune produce down low didn't help the situation.
Since then I'm on a new engine with CBC with a Stage 2 Apline tune. (basically a GTS tune) Compared to VF this tune is much more linear in its power delivery. No issues after ten or so track events. Knock on Wood.
I also no longer have the transmission shift setting at it's most aggressive. I keep it in the second setting. I believe abrupt changes to the drivetrain may contribute to SCB. Who knows though.
In the video below you'll notice I wasn't being hard on the engine at all.
