Hi I have been attempting to finish need 4 speed for the past 3 days.
I completed it thanks to the turbo mode I now have all the cars fully upgraded to do the turbo mode.
You need to go into a race when you select your car you press triangle up and cross.
Hold it till you are in the race to use it drive and hold up when you press up you will go twice as fast.....
