Ahh a Haltech fanboy I see.
Hand controller aint a joke, you get a good tuner who knows what hes doing you dont NEED to touch ANYTHING tune wise. You watch the hand controller and read out 8 different sensors that are going on in the engine.
Have had a Nistune, now I run a PFC. Won't touch a Haltech, too annoying to tune, shit with stock CAS, don't want 8 expander boxes sitting in my foot well just to run a couple of extra sensors. If you could look past the internet fanboy and sales pitch of these ECUs, you would understand that a PFC does EVERYTHING you NEED it to do.
