Personally, like to shift at 3k when the engine's cold. (4500 past 140 and up to redline once it's past 180) You really shouldn't be putting power to the wheels under 2k. It's pretty hard on the internals.
Once warmed up, you should be taken 1st at least to 3500 on a gentle start. Shift slow and gentle as this is a pretty finiky transmission and does not like to be rushed. If you feel a crunch or grind it's not liking what you're doing.
Also, I lowered the clutch engagement position of the pedal to make the feel better.
Clutch Peddle Position Adjustment
Clutch pedal too soft/no feel? Remove the helper spring!
And don't spin the tires, they're hella expensive!
