How to use a two step?

[sn95gt19]

you have a momentary button, so when your staged just push the button and floor it, and it will stay at whatever rpm the chip is. the whole point of a 2 step is that you'll have consistant launches and you wont have to worry about playing with the gas pedal to get the rpm right. this way you can just floor it. when your ready to launch let off the button. and pop the clutch.
it will help your 1/4 mile times if you can hook launching at that rpm, and no it wont damage your engine, its just a 3500 rpm rev limiter, and msd pulls spark not gas so you dont have to worry about running lean.
