55 mod by default came with Lee' 'AI Speed Control' patch installed. This is what it does:
AI speed is a complex interaction among several .ini files and the gpl.exe code. The prime determinate of AI speed is the driver's hype setting; however, it is often difficult to match the driver's cornering speed to his straight line speed. Quite often, if the driver's straight line speed is set correctly by his hype setting, then his corner speed is too fast. This patch lowers the corner speed.
Specifically, it lowers the AI cornering speed goal to 90% of the track's race.lp file value. The goal speed on the straights is not changed.
I found this patch useless for 55 mod because it makes AI cars too slow in corners. Without it it more fun to race with AI cars.
So to try to remove this patch xml from <gpl folder>\Mods\GEM+\gpl55\
folder and rebuild gplc55.exe with GEM+. I'm not at home and can't confirm xml name but I think it called 78L.xml.
