You can improve on your 60' time, but that might be dependent on the age of your tires. Your 1/4 mile time is pretty good already for a Typhoon. You could datalog your ECM to see if their are additional improvements, but with your timeslip I bet it looks pretty good.
you should be able to get the 60ft down a 10th. Experiment with the launch. Hook a lock up switch up to your obd connector that's good for a tenth up top. Search on here to find out how to do that its easy.
If you're actually racing you're reaction time could improve a lot by leaving on the third yellow. If you're just going for time and speed it doesn't matter. Sit there and build a little boost. What is your launch RPM?
