Allright i seem to have a major problem since i used the Mega trainer. when i drive any kind of Prototype races and i drive with a Audi R10 my car simply can't out run other cars, i used to just drive by, and it seems like all the other cars have increased acceleration, and mines the only one that's got decreased. I used the Mega Trainer once in Le Mans just for fun, to increase acceleration, and handling, also it seemed like it also effected the other drivers, in the same car, in this case Tom Kristensen, and Emanuele Pirro, just that their cars, got faster acceleration than mine.
And well i drove another prototype race and could only get to 3rd while some random driver in the standard prototype car ( the one you get in National ARL) could outrun me easy he was 10 seconds in front of me, and it sucks. :P I hope i described my problem good enough.
