im not pushing it that hard!! its just to maintain speed going up a slight incline. im not hotrodding it or trying to speed up just trying to maintain my speed. my rpms only go up a few hundred to maintain my speed. if thats pushing it hard for GP's then i take back all the good things ive said about these cars. none of my other cars have done anything close to this before. and fyi...i tried doing what you said today and still got the same results!!!
