shouldn`t my stall be helping my time on the strip?

i went to the track friday night and i run 8.56 8.57 8.57 8.64 and all of my 60 ft times are 1.90 to 2.10 i didn`t spin much at all.i just installed a new stall in the car a i was hoping for alittle out of the car.because the car was running the same times before i installed the stall. i don`t think that the stall is work what do yall think ? mark thanks
