If you have a tune launching from first gear is useless due to traction. Rev to about 2500K while power braking and then release brake pedal. I still spin at around 20 MPH but that's with street tires. If you rev any higher than 2500K you'll just start spinning your tires as if you were trying to do a burnout.
