the pcm's should already be programmed for your application and they wil relearn your style of driving as you drive. If you ever have a question that wasn't answered correctly just recontact me if i ansered it and it will right to me so as to not waste time. Just make sure the pcm is correct for your car like engine/trans combo. It shold be ok.
