To wheelie start in fourth gear and just before you would normally shift to 5th brake go to 3rd and hit the gas then shift to 4th5th etc. if you do this right you would wheelie.
The tune
Arodynamics front all the way left and back all the way right
Transmission all the way left for every thing top speed 100mph
This is just a general wheelie tune not for a specific car. Hope it helped
