First off there are a couple things in your way...the TCS was the first and you've already figured that out.
The next is the rev limiter and in general a computer that does not want you to spin the tires
You can eliminate much of that with a tune (move the rev points and in general free up some torque).
Then you are at the point where you CAN do it consistently - but pretty much every method is hard on brakes, engine, tranny so be sensible (yeah its fun but you want your car to last a bit).
DO NOT do a neutral shift and you don't need to push the throttle to the floor.
Pumping the brakes a few times before you start is a good idea.
Then, do a brake stand and get the RPMS up as high as you are comfortable and the tune will allow - I've done 3k but it was not my car
Then release the brakes slowly and go.
The other option is get a 5-speed
With a stock V6 you can turn your wheel a bit and get a one-legger but where's the fun in that right?
