Turbo Shifting "M/T Only"
Ever get tired of it when you slam into the back
of an innocent motorist and your car isn't that
quick to get back up to speed? Well, here's
something you can do to get up to speed a lot
quicker. When you hit the back of a car, or a
wall head on, reset your car as quick as you
can, then, (while it's in first gear, shift it
in to netruel "N", keep your gas all the way
down, let the car rev up to the red line, then
kick back into first gear, you'll tear off so
fast it will make your head spin. NOTE:
Sometimes the engine sound doesn't match, what
the needle says, just shift into first as the
needle hits red, that give you Turbo Shifting.
