not sure about lately but the procom units have issues of their own, do a search on it in here. I think most are preferring to go back to the oem unit, pricey but less likly to have issues with it. if you are replaing it at 56k miles thats not to bad given some of the history with our cdi, i think i would spend the 700 for the oem.
