just ask them if that is part of their programming for a stock bolt engine, and if it is, then no harm no foul, and you sound like you know what you're talking about.. if they dont (which i can't say not sure about their programming) i see no reason why they wouldnt be glad to make that change for you. If it is too much of a pain for them to do it that way, then you can contact matt at spartan, but at least give them the chance to do that. again, they are pro's and i'm sure they know this already, but just remind them again you dont want to lift a head.
