Many cars were modded throughout as the series went on, closer ratios for example, re maps, TB butterfly profiled, de wedged, stuff like that. Heard many stories of the 'cheating' from ex G40 Cup racers, not uncommon in all forms of racing really, VW Cup was rife with it too. Cars also got modded up abit more when it joined the super coupe cup with quite a few hidden mods.
So you'll find a fair few Cups that aren't the stock spec anymore.
