when i ran at sears point stock in my 2003 gt i ran a 14.2 since i have added; 3:73 ford racing gears, steeda pulleys, a C&L 85mm MAF tru flow, 70mm ford racing thorttle body, bbk off-road x-pipe, flowmasters, and 255/40-17(front) and 275/40/17(rear) Flakin tires with svt chrome rims....now i ran a 14.7 at sacramento. my check engine light is on and the diagonstic machine says theres a misfire in master cylinder heads 4 and 5 but i should i be running a 14.7? or somewhere in high to mid 13's and does the misfire have a lot to do with my slow time?

OBVIOULSY IF YOUR ENGINE IS MISFIRING ITS NOT GOING TO RUN 13'S!...
~What were the trap speeds?...The speed at the end of the 1/4 mile....
~Whats your 60ft times?
Get the Misfire fixed and then go back to the track... ![[patriot]](graemlins/patriot.gif)

Did you trap speed (MPH) change after you did the mods?
