Well I ended up swapping my 2.5l for a 4.0. I am currently running the pcm from the 95' donor with my cable speedo instead of the electric speedo. My questions is would I be getting better gas mileage using the 91/95' pcm with a digital speedometer? Since the speedometer goes thruogh the pcm vehicle speed might be a factor. With the pcm seeing no vehicle speed would this be an issue. Or am I just being over worried.
