Ok I know someone in here has a legitimate answer.... Are the stand alone harnesses and factory computer better or worse than say a fitech or holley sniper setup that replaces it. Pleas help

I'm very happy with my PSI standalone engine harness and factory PCM computer. It supports my engine and 4L60E transmission quite nicely. No complaints from me and I did not need to buy a separate transmission control module.
