If you still cant go full throttle in second anyway, then I would experiment with early shifting and seeing if you can do it without the car landing too low in the powerband in second. Otherwise, always shift as late as you can.

One thing I have noticed about my car, it doesnt like to shift while the wheels are spinning. I havent really sat down to think about that one... but I have observed that if I am in first gear banging the rev limiter from tire spin, its not going to let me into second (nasty grind) unless I let off for a moment. I assume the tires and drivetrain need to decelerate down for everything to be happy and allow the shift, just havent really thought about it yet.
