I have a "starting line enhancer" which is basically a throttle stop. It works through the delay box.
What it does is you stage and hit the transbrake button and mat the gas, but the car stays at a predtermined rpm. mine is 1200.
Then the delay box tells it half a second before the brake is going to release to open the throttle. It opens the throttle the same everytime and it doesnt matter if I am spotting someone 5 seconds it is very consistant that way and no more bogging down when you go to stick the gas.
I hope I explained it right..lol...
