An extra 100+ horsepower
I use this for drag settings, it may cause different effects in other styles. In the tune section for your car go to the engine part and then push the cam all the way up to advanced and then push the start and end boost all the way up. This will give you better performance and top end RPMs, it should also push up your horsepower by atleast 100. If it doesn't then upgrade all performance parts to level 3.
