Youre pretty much just going to have to feel how your car wants to be driven. Our cars usually launch good around 3.5k to 4k on the track. I shift at 7k (stock redline) and no lift off the gas during the 1-2 shift. Just a quick clutch and throw into second. Just that alone took about .5 off my track time. Spend a full day racing at the track and you should know what your car likes.
