I ran my car at the track and have raced a few people and my 240 seems to die off at like 70-80mph i ran a 13.78 at 94mph to me that seems to slow anyone have an SR with some mods that might know if that seems right or not i need help. i have a greddy front mount hard pipe kit exhaust , intake ,255 fuel pump and thats it everything else is stock at 7psi. 2.0 60 foot any ideas before i start to jack with my timing? or does the SR just not pulll hard up top...
