depends on your setup...when i was i/h/e i'd launch fairly high like around 4800-5000 rpms on kumhos. With boost i can only launch about 3000-3200 or i spin through 1st and second. Just try and launch about 4500 with the clutch halfway out but right before the friction point. Then let the clutch out slowly and when it looks up give it gas and let off the clutch. The key is to do everything in small increments, if you stomp/dump you'll always be stuck with a 2.3+ 60 foot.
