In Gran Turismo 1, when I make hybrids, very very often happen that the my car is "corrupted". Whit corrupted I mean that the car, when I try to accelerate, the car's RPMs will stuck to about 5.000-7.000rpm, don't let to start fast and when reach these RPMs when the car is launched don't go over, resulting a RPM limiter. Is caused because I use too many parts? Is caused also because I mix N/A and Turbo? Or because the car have a very high amount of HP? Is possible to fix?
