Weight reduction....do what ludeboy did and he run 14.9 with the ss. take out the front and back bumper supporter, light weight battery, no ac, no ps, no washer fluid, take everything out that you don't need (seats..), and run on empty gas tank (you actually have 3 gallons lelf when it at empty). Also, take a shit before you race.

Please let me know what else did I miss. Another thing is practicing your reaction skill so you can minimize the delay when you take off.
P.S. Why do you want to pull on other 5-speeds lude? Just pick on something else beside the lude.
Peace,
