Good kill
Never shift at 6500 rpm's you will run slower that way shift at 5200-5400.
You are probably running a mid to high 14
If you are the fastest in your town with a stock stang with a worn out tranny, thats just sad.
Dont take our criticism personaly alot of the guys here really know there stuff. Read the post and ask questions and you will learn alot there are alot of ways to tune your car and make it faster.
You still have much to learn having a stang will be a good learning experience.
Good Luck
