You can do the same thing with tuning if you want since all the 2 step does is cut spark to various cylinders and the unburned fuel is what spools the turbo when theres no load. Fatten up the tune or pull the timing way back for the launch and tah dahhh...boost comes up before you launch. If your engine management allows it just wire in a momentary button to actuate another set of fuel maps to richen it or timing maps to retard the timing.

I took the 2 step off my truck since I dont like the sound a V6 makes while its up against the box and once I got things sorted out I can build more boost than the brakes can hold (automatic trans) anyways. Besides a V6 exhaust note sounds bad enough as it is without something like a two step making it worse .

silvcobra,

Your car still has a blower on it and you havent converted to a turbo correct? If so comparing a blower to a turbo is apples and oranges. A blower will make boost with no load very easily while a turbo motor will make very little if any unless you start loading the motor down with the weight of the vehicle (ie give the motor something to strain against) or get unburned fuel into the turbine side so it can light off. Turbos require heat as well as the flow of exhaust gasses to spin it where as a blower is ran off the crank (usually) which means the harder you twist the motor the faster the blower spins producing more air flow (ie boost).

Not being an ass here just pointing out that its not a matter of "just rev it to where you want to leave" on a turbo vehicle.


The alf picture is just freakin nasty.
