I came across this while screwing around in Paradise City and it really works. First host an online freeburn event. Then wait for one person to join and then create a long race that starts near the freeway and has traffic off using a speed car go to the freeway and just go in oncoming untill you get 20x burnouts

Also if you have any other hints on achievements please post them here

no u

There's also wall corners you can run up against to get this achievement, or go to the fountain Downtown.

Every time I start to get a boost chain, it stops at 3x. For no explainable reason.

thanks, gotta try that one.

"There's also wall corners you can run up against to get this achievement, or go to the fountain Downtown."

You god damn boosters,
Just go into the wildcats stadium and get the mean drift going with the boost.

It's possible to boost drift in a small area? I always tried to get this achievement on the I-88, I never knew that you can boost chain while spinning in the Wildcat Stadium. How difficult is that?

I did it the hard way... on I-88.
