01 s-trim mustang FUEL PROBLEM AT SHIFT

01 mustang with s-trim. everytime im racing i let off the fuel to shift.. when i punch it in the next gear fuel pressure goes to 0 for a second and the car studders before going again. i kinda understand the general problem. is there a fix???????
 
same problem i had!!! mine would fall on its face for a split second between shifts and then pick up again. it really sucked especially when running at the track.

i found a 100% solution for mine.
