I think my car should run faster then it does. I ran low 16's with stillen headers, K&N intake, Magna Flow cat-back exaust and z rated tires. Is there something wrong with my car because I heard I should be running low 15's and high 14's. I dont feel that much of a significant gain in power at higher RPM's. I'm going to get my cat checked, and if its not that then I dont know what it would be.
