Wow that's really safe.

its not unsafe when done in the right places. and i love doing it when someone is up my cars backside... they usually stay away at the next light.

and with the no lift shift you can do that driving down the street

2 step

So with the osiris you have to be in one map foot to the floor hitting the rev limiter that's set low since it isn't actually a 2 step and just as the light goes green u have to time it perfectly so it clicks back into the other map. Not really a feasible option. Get the wot box

i didnt know you could switch maps like that. i wanna go play with mine.

^ if the other maps Arent tuned you might not wanna Mess with them

2 Step rev limiters are primarily used in drag racing applications. Lower Rev limit is engaged when line locks or Trans Brake applied to keep car staged correctly. When car is launched and trans brake or line locks released the engine will go to upper rev limit.
