ok im having trouble getting past 100mph. my exceleration isnt the greatest but its ok when i get to 100mph it just wont move any more its like i let off or something but really its to the floor . i would like to know if its just the motor i have or if there is something wrong with my car. either way i would like to fix it so if there is anyone who has any suggestions i would greatly appreciate it . i just recently bought this car and it is my first import so i am not at all familiar with them . but so far my mods are cold air,exaust,act lightwieght flywheel,stg 1 exedy clutch. i dont know if these would make a difference in why this probblem exists.
