Has anyone replaced a pcm with a police p71 ?
What was the outcome? |

Contrary to what a lot of people thing,there is not much difference from the p74 and p71. The p71 has a higher idle speed, higher shift points of the trans, and a higher top end. All this is from the pcm. Changing the pcm won't do a lot of improvements. That is unless your old pcm is bad.
