Doesn't the engine need a signal from a VSS to run at its highest potential??? I know it doesn't HAVE to have it, but I thought it was much better if you did. The engine needs to know what speed its going (not just RPMs) to tune itself properly. I have read this on a couple different sites, here is a quick link that keeps it pretty brief. Read the first paragraph. If I'm incorrect on this then by all means let me know, I'm in the middle of the same swap!
