ok, with what i have in my sig, i wanted to know if the smarty is going to be a big difference or will i not feel much difference since i cant use the smartys timing because of my drag comp. if i would feel a big difference , is there any one thats close to my side of town that would mind giving me a ride in his truck or mabey lettin me try the smarty 4 a couple of miles. any advice is greatly appreciated. thanks in advance.

 

the smarty would be quite noticable i would think. i just drove a truck with a comp and 150 injectors and i downloaded my smarty on it.

i would get before the smarty, but afterwards, (with the smarty) it was much quicker.
