if your auto= ease out on the gas from the dig dont slam the gas till you feel the car hook

if your 6mt= same goes for the 6mt hold the clutch out to the point that car is ready to roll. Take the rpm tp 2100 and follow the auto^^ instructions.

that should get you hooked up and ready to go.

Rev up anywhere from 3000-5000, dump the clutch and ease off the gas to about 2000, hit the brakes and apply more gas (until you get the torque you need)

Get a procede and reduce the user torque for 1st gear to 80% or 70%. You can adjust 2nd gear as well and it would be cheaper than a LSD.
