Less is more and smooth is faster. If you're spinnin' you ain't winnin'.
Personally I find Revo's figures to be realistic and their tune has that lovely press the pedal harder for more acceleration feeling. Some tunes are littered with flat spots, are all top end and no bottom end, and vice versa. And they retain the factory pedal mapping, too. Not a fan of the 'linear' pedal map at all.
