Line lock or leave as is?

I do the same thing at the red lights. Linelock on, two step on. Hold the button on the shifter and mat the pedal!

I have my two step set just below the stall so no tire spin but it leaves like a striped *** ape with its *** on fire!

When I wanna use linelock to heat (or melt) the tires I just flip the two step switch off.
