Hi all,
Got a XC850TF for the euros warmup. It's highly adjustable, but you'd need to know what your at when setting it up.
The power came in really smoothly at the bottom end and the boost was really tunable to exactly what I needed.
Only thing I noticed was if you ran 10+ degrees of boost timing with an LRP X12 motor, everthing got a bit hot. You;d expect the motor to get hot, but the speedo was a bit to warm for my liking (air temp of 24 degrees) - think I'll be buying the optional fan.
