I drop TP to 25psi on my stock tires and give them a light haze burnout. Just enough to start the smoke.
A tune would do you wonders for your ET's. You probably don't want to do it but just sayin.
I usually launch between 2300-2500 and let out the clutch a lot similar to leaving quickly at a stop light
Also I feel your pain on the rev limiter at the stripe so I started shifting to 4th.
I'm still a beginner myself but talking to people here and at the track like you have has helped alot. Here is my fast slip from doing these. This is my fastest time to date. And a short video of beating a mustang lol.
I'm car #396
Hope some of this helps and gives you an idea of where you will be with a tune.
